How to Schedule an Instagram Carousel Post

Step by step

1. 1

   Prepare and size your carousel slides

   Export every image or video clip at the same aspect ratio — 1080 × 1080 px (1:1) or 1080 × 1350 px (4:5 portrait) are the most common choices as of June 2026. Portrait 4:5 claims more screen space in the feed and tends to perform well. Keep each image under 8 MB and each video clip under 60 seconds, consistent with Instagram’s current upload limits.

   Tip: Use the free carousel splitter tool to cut a wide panorama or a long infographic into perfectly aligned slide segments — the split lines will be invisible when users swipe through.

2. 2

   Connect your Instagram Business or Creator account

   In SocialKit, open your workspace settings and connect Instagram through the official authorization flow. As of June 2026, this routes through your linked Facebook Page — you will select the Page, then the associated Instagram account. If your Instagram does not appear, the most likely reason is that it is a personal account or is not yet linked to a Facebook Page; fix both in the Instagram and Facebook apps, then try again.

   Tip: Once connected, check that SocialKit shows the correct handle and profile photo before you schedule anything — a wrong-profile post to a live audience is hard to walk back.

   Open the composer and choose Instagram as the destination

   Click "Create post" in SocialKit and select your Instagram account as the publishing target. If you plan to cross-post the same carousel to Facebook, select both accounts here — SocialKit lets you customize the caption per platform before you confirm. Keep Instagram selected for the steps below.

4. 4

   Upload your carousel slides in the intended order

   In the media section of the composer, upload multiple files in the sequence you want them to appear. SocialKit treats the first file as the cover slide — the one shown in the grid and when someone lands on your profile. As of June 2026 the Instagram API supports mixed photo and video items in one carousel for eligible accounts; if your combination triggers an API rejection, SocialKit will flag it so you can switch to a photo-only set.

   Tip: Drag to reorder slides after uploading if you change your mind about the sequence — no need to start over.

5. 5

   Write your caption and add a first comment (optional)

   Type your caption in the text field. Instagram captions support up to 2,200 characters as of June 2026; the first line is all that appears before the "more" truncation, so lead with the hook. If you prefer to keep your caption clean and put hashtags elsewhere, SocialKit’s first-comment scheduling lets you auto-post a separate comment the moment the carousel goes live — use that slot for your hashtag block.

   Tip: The caption applies to the full carousel, not individual slides. If your slides tell a sequential story, write the caption to frame the arc rather than describe one image.

6. 6

   Pick a date and time using best-time data

   Set your publish date and time manually, or consult the best-time guidance for your audience — the /best-time-to-post/instagram page gives aggregated data by day and hour as a starting point. Your own Instagram Insights are the most reliable signal once you have posting history, because peak windows differ per niche and follower geography. SocialKit confirms whether the post will auto-publish or deliver a mobile reminder depending on your account setup.

   Tip: Carousels tend to generate extra time-on-post as users swipe through, which can signal quality to the algorithm. Scheduling at a moment when your audience is actively scrolling increases the early engagement that matters most.

7. 7

   Confirm the schedule and verify in the calendar

   Click "Schedule" to queue the carousel. Open SocialKit’s content calendar to confirm the post appears at the right date and time. As of June 2026, auto-publish is available for Instagram Business and Creator accounts connected through the Instagram Content Publishing API; if you see a "reminder" indicator instead, it means your account type or a specific configuration is not eligible for full automation — SocialKit will send a push notification to your phone so you can tap to post natively at the right moment.

Best practices

• Keep all slides in the same aspect ratio before uploading — mixing orientations within one carousel is not supported by the Instagram API as of June 2026 and will cause an upload error.
• Lead with a visually arresting cover slide; it is what appears in the grid and in the feed before anyone taps. A strong cover increases swipe-through rates more than any other single variable.
• Write the caption to tease the full sequence rather than describe just the first slide — give people a reason to swipe to the end, because completion signals quality to Instagram’s ranking system.
• Schedule carousels during your audience’s active hours based on your own Instagram Insights data; aggregated best-time figures are a useful starting point but audience geography and niche matter more than generic benchmarks.
• Use the first-comment slot for hashtags if you want a clean caption — there is no strong evidence that hashtags in comments vs. captions perform differently, so treat it as a formatting preference rather than an algorithmic optimization.
• After a carousel posts, check its insights after 48 hours rather than immediately; carousel reach and saves often accumulate over a longer window than single-image posts.
