Add a border to a photo

Instagram trims anything that doesn’t fit its shapes: feed posts can be square (1:1) or portrait up to 4:5, and the profile grid shows 3:4 tiles. A landscape photo either gets cropped or shrinks to a thin strip. Padding it to the right shape with a white border keeps the whole picture in view and gives your feed an even, gallery-like edge.

• 1:1 for a square post: the photo sits in the middle with white above and below (or at the sides).
• 4:5 for the tallest feed post: the most screen space a single photo gets in the feed.
• 3:4 to match the profile grid, so nothing is cut off in the thumbnail.

With a fixed shape, the canvas’s shorter side equals your photo’s shorter side, and the picture is scaled to fit inside the border. A 4032×3024 phone photo set to 4:5 becomes 3024×3780. Instagram resizes every upload to its own sizes, so for a smaller file you can also set Size to 1080 px under Export settings.

A border doesn’t have to be plain. Polaroid gives the instant-photo look: narrow sides, a deep bottom edge and room for a handwritten-style caption, which you type under More options → Caption. Film strip puts the picture between sprocket holes, and Browse all looks opens over 400 designs in 25 categories, from paper and tape to gilt frames, neon, holiday and wedding frames.

Make a frame match the photo

Many looks have their own colours under Look colours. Match video colours reads a palette from your picture (on your device) and recolours the look to suit it, which works just as well on a photo as on a clip. In Chrome and Edge on a computer, the eyedropper picks any colour straight from the preview.

Border width is a percentage of the photo’s shorter side, so the frame looks the same on a small screenshot and a 48-megapixel original. On a 4032×3024 photo, 5% is about 151 px on each side. Thin borders of 2 to 3% read as a neat keyline; 8% and more makes the frame part of the design.

• More options → Units → Pixels sets an exact width, for example a 50 px edge for a print shop.
• Turn off Same width on every side to set the top, right, bottom and left separately, such as a deeper bottom for a caption.
• Corner radius rounds the photo’s corners; the border shows through, so they stay round in every app.
• Inner padding adds a mat in its own colour between the photo and the frame, the way a framer mounts a print.
• Drop shadow and Outline lift the picture off the border.

The photo is saved in the format it arrived in where a browser can write it: a JPEG stays a JPEG and a PNG stays a PNG, while HEIC and AVIF pictures are saved as JPEG. Change it under Export settings → Format: JPEG for small files that open everywhere, PNG for a lossless copy that keeps transparency, or WebP in browsers that can make it (Safari can’t).

Quality (50 to 100%, 92% to start) trades file size against fine detail for JPEG and WebP. Size keeps Full size unless you pick a smaller long edge such as 2048 px. Safari on iPhone and iPad can’t draw a canvas much over 16 megapixels, so a very large photo is saved there at the biggest size the browser allows.

The saved copy leaves out the camera, the date and any location your phone stored in the photo, so a framed picture you post doesn’t give away where it was taken. Your original file is not changed.

The built-in Photos apps on iPhone and Mac crop, rotate and adjust colour but have no border tool. In Photoshop, Image → Canvas Size with Relative ticked adds an even border in the canvas extension colour. Design apps such as Canva have frame elements you place a photo into, though the result is sized to the design rather than to your photo.

This page is quicker when you want an even border at the photo’s own resolution, a shape for a feed, or one of the themed looks, without installing anything or handing the picture to an online service.
