Instagram size guide

Instagram post and Reels sizes

Use portrait feed space while keeping a square option, then switch to 9:16 for full-screen Reels.

Instagram Reels size 2026: 1080 × 1920 vertical video

Build Reels on a 1080 × 1920, 9:16 canvas for full-screen playback. Export a separate 1080 × 1440 portrait or 1080 × 1080 square version when the same campaign also needs an Instagram feed post.

What the first version does

Feed acceptance range and export recommendation

Instagram accepts photos across a range of aspect ratios. The presets below select high-resolution working canvases inside that range; Reels use a 9:16 full-screen canvas.

Frequently asked questions

Should I use 3:4 or square for an Instagram feed image?

Choose 3:4 to occupy more vertical feed space, or 1:1 when the composition needs a square crop.

Does Instagram preserve every uploaded ratio?

Instagram documents an accepted photo ratio range and may crop unsupported ratios. Use one of the listed presets to stay within a predictable canvas.

Can I export the same creative for feed and Reels?

Yes. Export separate copies and adjust the crop position for each ratio so the garment and model remain framed correctly.
