Guide

Instagram image sizes users actually need

This guide turns broad Instagram size searches into exact export choices. It is meant to answer the requirement first, then hand off to the preset image tool.

Go straight to the right page

If you already know the task, use one of these exact tool or hub pages instead of reading the full guide first.

Start with Open the Instagram preset tool

Use the exact preset page when the destination is already known and you want the canvas set immediately.

Browse resize image in KB pages

Move here when the export still needs to fit a strict upload-size cap after the Instagram preset step.

Core Instagram sizes on this site

Square post: 1080 x 1080
Portrait post: 1080 x 1350
Story / Reel: 1080 x 1920
Landscape post: 1080 x 566

When to use each size

Use square when the layout needs a balanced feed crop and the source already centers well.
Use portrait when the goal is maximum feed height without switching to a story-style frame.
Use story or reel dimensions when the image needs a full-screen mobile canvas.
Use landscape when the content is naturally wide and should not be forced into a tall crop.

Recommended workflow

Start with the Instagram preset tool when the destination is known. If the image still fails an upload size limit after resizing, move into a KB target page to compress the exported result.
