How to Split Screenshots for Social Media

Learn the best methods for splitting long screenshots into properly sized social media posts — for Twitter threads, Instagram carousels, and more.

The Long Screenshot Problem

You have a long screenshot — a full-page website capture, a text conversation, a receipt, a leaderboard, a code snippet, or an article. It is far too tall and narrow to post on social media as-is. Instagram crops it to a square. Twitter shrinks it until the text is unreadable. Facebook compresses it into a blurry thumbnail.

The solution: split the screenshot into multiple segments, each properly sized for the platform. Post them as a carousel on Instagram, a thread on Twitter/X, or a multi-image post on LinkedIn.

Splitting Screenshots for Instagram Carousels

Instagram carousels support up to 20 slides. For long screenshots, split vertically so each slide shows a readable section. The ideal approach:

  1. Open the Carousel Maker
  2. Upload your long screenshot
  3. Select the number of slides — the tool calculates the height of each slide automatically
  4. Choose portrait (4:5) or square (1:1) format for maximum readability
  5. Download and post as a carousel

For text-heavy screenshots (conversations, articles, code), aim for 3 to 5 slides. Each slide should contain enough text to be meaningful on its own while maintaining reading flow across swipes.

Splitting Screenshots for Twitter/X

Twitter displays images at a maximum of 1200 x 675 pixels in the feed (16:9 ratio). Long screenshots need to be split into sections that are readable at this display size. Two to four images work best for a single tweet. For longer screenshots, split into more sections and post as a thread.

Use the Custom Grid Maker with 1 column and multiple rows to split a tall screenshot into horizontal strips. Each strip becomes one image in the thread.

Splitting Screenshots for LinkedIn

LinkedIn's document carousel feature allows multi-page PDF uploads that viewers swipe through. Convert your split screenshot segments into a PDF for the most polished LinkedIn presentation. Alternatively, post the split images as a multi-image post (up to 9 images).

Best Practices for Screenshot Splitting

Find Natural Break Points

Do not split blindly by pixel count. Find natural content boundaries — paragraph breaks, section headers, list item divisions, or conversation message boundaries. A split in the middle of a sentence forces readers to swipe mid-thought.

Maintain Readable Text Size

After splitting, each segment must be large enough for text to remain legible. If the text is too small, consider cropping the screenshot horizontally (removing unnecessary whitespace on the sides) before splitting. This increases the text's relative size within each segment.

Add Context to Each Segment

Each split segment appears as a standalone image in viewers' feeds. Add a small label or slide number ("1/5", "2/5", etc.) to each segment so viewers know there is more content and which slide they are viewing.

Crop Before Splitting

Remove unnecessary elements before splitting: browser chrome, status bars, notification banners, and irrelevant page sections. Tighter cropping means fewer splits needed and more content per segment.

Handling Different Screenshot Widths

Screenshots from different devices have different widths. Phone screenshots are typically 1080 to 1290 pixels wide. Desktop screenshots can be 1920 pixels or wider. Before splitting, consider whether the full width is needed or if you can crop to the content area for better readability on mobile.

The Carousel Maker and Custom Grid Maker both handle any input dimensions — upload your screenshot at its original size and the tools calculate optimal splits automatically.

Split your screenshots into social-media-ready segments — upload to the Carousel Maker and choose your slide count.
