How to Post on Instagram: A Step-by-Step Guide for Photos, Reels, and Stories (2026)

To post on Instagram, open the app, tap the plus (+) icon at the top of the screen, and choose what to post: a feed post, Story, or Reel. Select your photo or video from your camera roll, edit it with Instagram’s built-in tools, add a caption, hashtags, tags, and a location, then tap Share. This guide walks through every step in detail for each content type, plus how to post from a computer, how to schedule posts, and how to do it well as a business.

Instagram post types and specs

Before you post, it helps to know what each content type does and what its size and length requirements are. Posting the wrong aspect ratio is the most common reason a photo looks blurry or gets cropped badly. Instagram displays content in the feed differently depending on its format, so getting the dimensions right matters.

Vertical (4:5 and 9:16) formats fill more of the mobile screen and consistently outperform square in the feed. If in doubt, post vertical.

How to post a single photo on Instagram

The most common post type. Users upload photos to Instagram constantly, so the flow is well-established. Here’s how to post a single photo from start to finish.

1. Open the Instagram app and tap the plus (+) icon at the top of the screen (top-right on iOS, top-left on Android). On older app versions, the plus icon may be in the centre of the bottom navigation bar.
2. Select “Post” from the options at the bottom of the screen (other options include Story and Reel).
3. Choose your photo from your camera roll. To post a single photo, tap it once. Instagram will automatically crop to a square. To keep the original aspect ratio, tap the expand icon in the bottom-left of the preview.
4. Tap Next in the top-right corner.
5. Edit the photo. Instagram offers two editing tabs: Filters (preset colour treatments, tap to apply, tap again to adjust strength) and Edit (manual controls for brightness, contrast, structure, warmth, saturation, fade, highlights, shadows, vignette, tilt-shift, and sharpen).
6. Tap Next to move to the caption screen.
7. Write your caption. Captions can be up to 2,200 characters but only the first 125 show in the feed before “…more.” Captions provide context for images, so lead with the most important detail. Add hashtags, emojis, and line breaks for readability.
8. Tag people by tapping “Tag people” and tapping the photo to add a tag.
9. Add a location by tapping “Add location.” This is one of the highest-impact discoverability tactics, since locations appear in search and in the location’s own feed.
10. Choose where to share. You can cross-post to Facebook automatically by toggling it on.
11. Tap Share in the top-right. Your post is now live.

Pro tip: If you make a mistake after posting, you can edit the caption, tags, and location at any time, but you can’t change the photo itself. Tap the three dots on the post and select “Edit.”

How to post multiple photos (a carousel post)

Carousels let you post up to 20 photos or videos in a single post. They consistently get higher engagement than single-photo posts because viewers swipe through them, and Instagram now reshows carousels to people who didn’t swipe through them the first time.

1. Open the app and tap the plus (+) icon.
2. Select “Post.”
3. Tap “Select Multiple.” The icon looks like stacked squares, in the top-right of the photo grid. You can now select up to 20 photos or videos.
4. Select your media in the order you want them to appear. Numbers appear on each item as you tap them. To change the order, deselect and re-select.
5. Tap Next.
6. Edit each item individually. You can apply different filters or edits to each slide by tapping it. To apply the same filter to all slides, tap the filter on slide one and select “Apply to all.”
7. Tap Next to move to the caption screen.
8. Write your caption. Carousels only get one caption that applies to the whole post. Hook the reader in the first sentence and tell them what’s in the carousel (“Swipe to see all five”).
9. Add hashtags, tags, location, and cross-posting as with a single post.
10. Tap Share.

Pro tip: Instagram reshows carousels to viewers who didn’t swipe through the first time, sometimes with a different image at the front. Make every image in the carousel strong enough to stand alone.

How to post a Reel on Instagram

Creators publish Reels for engagement because they’re Instagram’s highest-reach format, appearing on your feed, on the Reels tab, and in the Explore tab. Reels are how people who don’t already follow you find your content.

1. Open the app and tap the plus (+) icon.
2. Select “Reel.”
3. Record or upload your video. To record in the app, hold the shutter button (you can record in segments). To upload an existing video, tap the gallery icon in the bottom-left and select from your camera roll. The in-app camera typically caps at 3 minutes; uploaded videos can run up to 20 minutes.
4. Edit your Reel. The Reel editor includes Trim (adjust start and end of each clip), Reorder (drag clips to change sequence), Music (add a track from Instagram’s library, trending audio significantly boosts discoverability), Voiceover (record your own audio over the video), Text (add captions, titles, annotations, with timing for each), Stickers (polls, questions, locations, mentions, hashtags), and Effects (AR filters and visual effects).
5. Choose a cover. Tap “Cover” before sharing. Pick a frame from the video or upload a custom thumbnail (1080 × 1920 px). The cover is what people see when they land on your profile grid.
6. Tap Next to move to the caption screen.
7. Write your caption (up to 2,200 characters) and add up to 5 hashtags. Important: Instagram formalised a hard 5-hashtag limit in December 2025 (down from 30), so using more than 5 can actively reduce reach.
8. Tag people, add a location, and choose cross-posting options.
9. Tap Share.

Pro tip: Reels with on-screen captions get measurably higher engagement because most people watch Reels with the sound off. Always add text captions to spoken content. And although the maximum length is 20 minutes, the algorithm still favours Reels under 90 seconds for discovery.

How to post a Story on Instagram

Stories appear at the top of the Instagram feed and last 24 hours. Stories disappear after 24 hours unless saved as a Highlight, and the format is designed for casual, real-time content. They’re the highest-engagement format for community building.

1. Open the app and tap the plus (+) icon.
2. Select “Story.”
3. Capture or upload your content. Tap the circular shutter button to take a photo, hold it to record a video (up to 60 seconds per Story slide), or swipe up to upload from your camera roll.
4. Edit your Story. Stories have the richest editing tools of any Instagram format: Stickers (polls, questions, quizzes, countdown timers, location tags, hashtag stickers, mention stickers, music), Text (multiple fonts, colours, and effects), Drawing (freehand annotation), Filters and effects (AR effects, face filters, colour treatments), and GIFs from GIPHY’s library.
5. Add interactive elements. Polls and questions are the most engaging because they prompt responses. Polls give you data; questions let you reply by re-sharing the question and your answer as a new Story.
6. Choose your audience. Tap “Your story” to share publicly, or “Close Friends” (green star) to share with a private list you’ve curated.
7. Tap Share or “Your Story” to publish.

Pro tip: Save your best Stories as Highlights. After posting, go to your profile, tap “New” under your bio, and group the Story with related Highlights (for example, “New Arrivals,” “FAQs,” “Events”). Highlights stay on your profile permanently and are valuable real estate for businesses.

How to post on Instagram from a computer

You can post to Instagram directly from a browser on a Mac or PC, which is useful if your photos and videos live on your computer.

1. Go to instagram.com in any modern browser (Chrome, Safari, Firefox, Edge) and log in.
2. Click the “+ Create” button in the left-hand navigation menu.
3. Drag and drop your photo or video into the upload window, or click “Select from computer.”
4. Choose your aspect ratio (original, 1:1, 4:5, or 16:9).
5. Edit your media using the browser-based filter and adjustment tools. The desktop editor has fewer options than the mobile app but covers basic cropping, filters, brightness, and contrast.
6. For multiple photos, click the multi-image icon and drag in additional files (up to 10 currently from desktop; mobile allows up to 20).
7. Add a caption, hashtags, location, and alt text in the right-hand panel.
8. Click Share.

A few limitations worth knowing about desktop posting:

• You can post feed posts and Reels from desktop, but not Stories.
• You can’t add Instagram-library music to videos from desktop.
• You can’t schedule from the native Instagram desktop interface, use a scheduling tool for that (covered below).
• Some advanced Reel editing features (effects, stickers, trending audio) are mobile-only.

How to schedule Instagram posts

If you post regularly, especially as a business, scheduling posts in advance is a major time-saver. There are three legitimate ways to schedule, only one of which is built into Instagram itself. All three support feed posts and Reels but not Stories, and all require a Business or Creator account.

Option 1: Native Instagram scheduling

Instagram added native scheduling for Business and Creator accounts in 2023. In the post creation flow, after writing your caption, tap “Advanced settings” then “Schedule” and select a date and time up to 75 days in advance. Works for feed posts and Reels. Not available for Stories.

Option 2: Meta Business Suite (free, native)

Meta’s free scheduling tool for Facebook and Instagram business accounts, working on both desktop and mobile. It supports feed posts (single and carousel) and Reels. Stories cannot be scheduled natively and remain mobile-only. To use it, go to business.facebook.com, link your Instagram account, click “Create post,” select Instagram as the destination, prepare your post, and choose “Schedule” rather than “Publish.” Requires an Instagram Business or Creator account (free to convert in Settings, Account, Switch account type).

Option 3: Third-party scheduling tools (paid)

Tools like Buffer, Later, Hootsuite, Sprout Social, and Planoly let you schedule across Instagram and other platforms from one workspace. Useful when you’re managing multiple accounts, need team approval workflows, or want analytics across platforms. The caveat: these tools schedule through Instagram’s API, which has restrictions, and Stories scheduling usually requires you to receive a mobile notification and tap “Publish.” It isn’t fully automated.

Pro tip: If you’re scheduling for engagement, use Instagram’s own analytics or your scheduling tool’s data to find the times your specific audience is most active. Generic “best time to post” guides are usually wrong for your account.

How to post on Instagram as a business

Posting as a business is mechanically the same as posting personally, but the choices you make at each step matter more. Businesses promote products through posts, and the difference between a post that converts and one that doesn’t usually comes down to setup decisions rather than the photo itself.

Switch to a Business or Creator account

Personal accounts can post normally but lack analytics, contact buttons, ad capability, and native scheduling. Switching is free and reversible, just go to Settings, Account, then Switch account type. Business accounts are better for retailers, service providers, and B2B brands. Creator accounts are better for personal brands, influencers, and individuals who want analytics without contact buttons.

Set up your profile properly

• Profile photo: your logo (1:1 square, displays at 110 × 110 px on profile, so file should be at least 320 × 320 px).
• Bio: under 150 characters. Lead with what you do, who it’s for, and a clear call to action.
• Link in bio: use a single link or a “link in bio” tool (Linktree, Beacons, or Sprout Social’s SproutLink) to route to multiple destinations.
• Highlights: organise Stories into permanent Highlights with consistent covers. Valuable profile real estate.

Write captions that drive action

Followers interact with published posts when the caption gives them a reason to. Lead with a hook in the first 125 characters (the bit visible before “…more”), include a clear call to action in every post (“Tap the link in bio,” “Save this for later,” “Tag someone who needs to see this,” “Comment your favourite below”), and match the caption length to the content type. Reels tend to do better with shorter captions; carousels can carry longer ones.

Use hashtags strategically (max 5)

Instagram formalised its hashtag limit at 5 per post in December 2025 (down from 30). Hashtags improve content discoverability, but only when used the way Instagram now expects. Mix two types: broader high-volume tags (like #GraphicDesign with 50M+ posts) to extend reach, and niche specific tags (like #ManchesterDesignAgency) to reach a more targeted audience. Avoid banned or shadow-banned hashtags, since Instagram occasionally restricts hashtags due to misuse and using a banned one can limit your post’s reach.

Tag locations, products, and partners

Locations boost local discoverability. Product tags (available in Business accounts with Instagram Shopping) link directly to product pages within the app. Tagging collaborators or partners adds another discovery path through their followers.

Post at the right times

The algorithm prioritises engaging content, and early engagement is what tells the algorithm a post deserves wider distribution. Use Instagram Insights (Business or Creator account, Insights, Audience) to see when your audience is online. The “best time to post” depends entirely on your audience, not generic advice.

Track what’s working

Insights show reach, impressions, engagement, profile visits, and follower growth at the account level, and impressions, reach, engagement, saves, and shares at the post level. Pay particular attention to saves and shares, since these are stronger algorithmic signals than likes.

Common Instagram posting problems and how to fix them

Why is my Instagram post blurry?

Most likely caused by uploading an image smaller than Instagram’s recommended resolution. Use at least 1080 px wide for the long side. Also check that “Data saver” is turned off in Settings, Account, then Cellular Data Use.

Why is my photo getting cropped?

Instagram defaults to a square (1:1) crop. Tap the expand arrows in the bottom-left of the preview to switch to portrait (4:5) or original aspect ratio.

Why can’t I see the music option on my Reel?

Music libraries are restricted on Business accounts to avoid copyright issues, with only “commercial use” tracks available. Personal and Creator accounts have access to the full library. Switch account type or use original audio.

Why is my post not getting any reach?

Most common reasons: posting at low-activity times for your audience, using more than 5 hashtags (Instagram now actively suppresses these), posting too frequently (the algorithm de-prioritises accounts that post multiple times within a few hours), or being affected by shadowbanning. Check Insights for unusual patterns.

Why am I capped at 10 photos in my carousel?

Your app needs an update. The 20-item carousel limit was rolled out gradually from 2024, and accounts on older app versions remain on the previous 10-item cap. Update Instagram in the App Store or Play Store and the higher limit appears automatically.

How do I delete or edit a post I’ve already published?

Tap the three dots on the post. To edit, tap “Edit.” You can change the caption, tags, alt text, and location, but not the photo or video itself. To delete, tap “Delete.” Deleted posts cannot be recovered.

Frequently asked questions

How do I post on Instagram from my phone?

Open the Instagram app and tap the plus (+) icon. Choose Post, Story, or Reel. Select your photo or video, edit it, add a caption and hashtags, tag people and a location, then tap Share. The full step-by-step is above.

Can I post on Instagram from a computer?

Yes. Go to instagram.com in any browser, click “+ Create” in the left menu, drag in your photo or video, edit, add a caption, and click Share. Desktop supports feed posts and Reels but not Stories.

How many photos can I post in one Instagram post?

Instagram allows up to 20 photos or videos per carousel post in 2026. Desktop currently supports up to 10. To post a carousel, tap “Select Multiple” after choosing your first photo. If you’re still seeing a 10-item limit, your app needs an update.

How do I post a Reel on Instagram?

Tap the plus (+) icon and select Reel. Record or upload a vertical (9:16) video, add music, text, stickers, or effects, choose a cover image, write a caption with up to 5 hashtags, and tap Share. Reels can be up to 3 minutes when recorded in-app and up to 20 minutes when uploaded, although the algorithm still favours Reels under 90 seconds for discovery.

How do I post a Story on Instagram?

Tap the plus (+) icon and select Story. Take a photo or video, or upload from your camera roll. Add stickers, text, polls, music, or filters, then tap “Your Story” to share. Stories disappear after 24 hours unless saved as a Highlight.

Can I schedule Instagram posts?

Yes. You can schedule feed posts and Reels (but not Stories) through Meta Business Suite for free, through the Instagram app’s native scheduler in Advanced Settings, or through third-party tools like Buffer, Later, or Hootsuite. You need a Business or Creator account.

How many hashtags should I use on an Instagram post?

Instagram formalised its hashtag limit at 5 per post in December 2025 (down from 30). Use 3 to 5 relevant hashtags, mixing broader tags (high volume) with niche tags (targeted reach). Using more than 5 will actively reduce your reach because Instagram now treats over-tagging as a spam signal.

What size should Instagram photos be?

Minimum 1080 px wide for any format. The optimal sizes are 1080 × 1080 px (square 1:1), 1080 × 1350 px (portrait 4:5), and 1080 × 1920 px (Story or Reel, 9:16). Vertical formats consistently outperform square in feed.

How often should businesses post on Instagram?

Quality matters more than frequency. A common range is 3 to 5 feed posts per week plus daily Stories, but more important is consistency. Posting once a week reliably is better than posting daily for a month then disappearing.

Can I post the same content to Instagram and Facebook?

Yes. When posting, toggle on “Facebook” before tapping Share, or set up automatic cross-posting in Settings, Accounts Centre. Note that the optimal format and tone for each platform differs, so cross-posting works best when the content suits both.

Need help designing what you post?

Posting on Instagram is mechanically simple. Posting well, with on-brand graphics, consistent visual identity, and content that stops the scroll, is what separates a profile that builds a business from one that quietly fills up the camera roll.

Design Cloud’s social media design service creates branded Instagram posts, carousels, Stories, and Reel graphics for marketing teams producing content at volume and for agencies managing client Instagram accounts. For Reels-heavy accounts, our social media video editing team handles the cutting and motion work. All on a predictable monthly subscription, with UK-based full-time designers, instead of agency project pricing or hiring a designer in-house.
