Image Stitching Online for Social Media: Platform by Platform

Why a single stitched image beats multiple uploads

When you upload several photos separately, the platform decides how to crop and space them. A single stitched image keeps you in control. Your spacing stays exact, your order stays fixed, and your composition reads as one thing instead of a random sequence.

It also looks more intentional. A clean grid tells the viewer you meant to do that.

Instagram: feed vs Stories

For the feed, stick with 1:1 square or 4:5 vertical. A 2x2 grid works well for four related shots. A vertical stack is perfect for a before-and-after or a short tutorial where people swipe up.

Stories are 9:16. A vertical stitch of two or three images fills the screen without awkward black bars. Just keep faces and text away from the very top and bottom edges.

Pinterest: go tall or go home

Pinterest rewards tall pins. A 2:3 or 1:2 vertical stitch can put a hero image at the top and detail shots below. The longer the pin, the more room you have to tell a visual story.

One warning: do not export absurdly wide. Pinterest will scale it down and the small details will turn to mush.

Twitter/X and Facebook: wide is your friend

Horizontal stitches work well on Twitter because the timeline is wide. A side-by-side comparison or timeline graphic fits the format naturally. People do not have to tap to see the whole thing.

On Facebook, 1200x630 is still the classic share-image size. Stitch two or three images into that ratio and you get a clean link-preview look.

Margins and background color are not decoration

Do not ignore the gap between cells. A small margin—around 4 to 12 pixels—separates images without breaking the grid. A larger margin gives you a gallery-wall effect.

Background color matters too. White is safe for product shots. A soft gray or brand color can make the grid feel designed instead of default.

Start with the photo count, then the width

Most stitching tools group templates by how many photos you are using. Pick that first, then adjust the total width to match your target platform. Preview before you download so you can catch spacing issues early.
