How to size images for Instagram

4:5 is the feed size

1080 × 1350 takes the most room in the feed of any size Instagram's publishing API accepts (4:5 to 1.91:1), so it works from the app and from scheduling tools alike.

3:4 fits the new grid

Since 2025 the profile grid shows tall 3:4 tiles, and the app accepts 1080 × 1440 uploads. Tools posting through the API may crop a 3:4 photo back to 4:5.

Stories and Reels need a safe zone

At 1080 × 1920, keep text out of the top 14%, the bottom 35% and 6% on each side, where Instagram puts the profile, buttons and caption.

Example: “A 4,032 × 3,024 phone photo for an Instagram post” = a 2,419 × 3,024 centre crop, saved at 1,080 × 1,350

Sizes checked on October 10, 2026, against Instagram's help centre and its publishing API.

FormatSize (px)RatioGood to know
Portrait post1,080 × 1,3504:5The best feed size. Instagram's publishing API takes 4:5 to 1.91:1, JPEG, up to 8 MB.
Tall portrait1,080 × 1,4403:4Matches the 3:4 profile grid. The app takes it; the API may crop it to 4:5.
Square post1,080 × 1,0801:1Shows whole in the feed; the 3:4 grid trims its left and right edges.
Landscape post1,080 × 5661.91:1The smallest image in the feed: use it only when the subject is wide.
Story or Reel1,080 × 1,9209:16Stories and Reels. Keep text out of the top 14%, the bottom 35% and 6% on each side.

Carousels take their ratio from the first image: size every slide the same. Instagram accepts up to 20 items in a carousel posted from the app.

Questions

Instagram image sizes, answered

1080 × 1350 pixels (4:5 portrait) is the best size for the feed. Instagram also takes 1080 × 1080 squares, 1080 × 566 landscape images, and, from the app, 1080 × 1440 (3:4).

1080 × 1920 pixels (9:16). Keep text and logos out of the top 14% and the bottom 35% of the frame, where Instagram shows the profile, buttons and caption.

1080 × 1440 pixels. Since 2025 the profile grid shows 3:4 tiles, so a 3:4 photo fills its tile without trimming. Scheduling tools that post through Instagram's API may crop it to 4:5.

Because its ratio is outside what Instagram shows in the feed (4:5 to 1.91:1), or because the grid shows a 3:4 tile. Resize it here to the exact format first.

320 × 320 pixels or larger, square. Instagram shows it as a circle, so keep the face or logo centred.
