Instagram Post Size Guide (2026): Exact Dimensions & Best Formats

As creatives, we pour our hearts, time, and meticulous attention to detail into every piece of work. There is nothing more annoying than exporting a beautiful illustration or design layout, only to watch Instagram pixelate the fine lines or awkwardly crop out your carefully planned composition.

To make sure your portfolio looks flawless on the feed, you need to master Instagram dimensions. Optimising your files not only preserves your line work and colour grading but also maximises your screen real estate, giving your art the space it truly deserves to shine.

Here is your definitive, creator-focused guide to setting up your canvases this year.

Instagram Cheat Sheet for Creators

• Reels & Stories (9:16 | 1080 x 1920 px): Best used for your interactive content, Procreate time-lapses, behind-the-scenes workflows, or portrait wallpaper freebies.

• Portrait Feed Post (4:5 | 1080 x 1350 px): The ultimate standard for character portraits, complex detailed paintings, and stand-alone typography layouts due to its massive screen presence.

• Square Feed Post (1:1 | 1080 x 1080 px): Ideal for vector icon designs, brand logos, flat vector art, and tileable pattern swatches.

• Landscape Feed Post (1.91:1 | 1080 x 566 px): Perfect for cinematic digital environment concept art, sprawling panoramic landscape photography, and website banners.

I hope this helps you keep your hard work looking exactly as intended!
