Every number on this page was checked against the platforms' current specs in September 2026. Two sizes cover 90% of what you post; the tables below cover the rest.
| Placement | Recommended | Ratio / notes |
|---|---|---|
| Feed post (portrait) | 1080 × 1350 | 4:5 — shown in grid as 1012 × 1350 |
| Feed post (square) | 1080 × 1080 | 1:1 |
| Stories / Reels | 1080 × 1920 | 9:16 — safe area 1080 × 1610 for text/stickers |
| Profile photo | 110 × 110 (min) | displays as a circle; upload larger, square |
An Instagram Story is 1080 × 1920 pixels, a 9:16 vertical frame; the same size is used for Reels and Reels covers. Instagram overlays its own interface on the top and bottom of the frame (your profile name and the progress bar at the top, the reply box at the bottom), so keep text, stickers and anything that must be read inside the central 1080 × 1610 safe area, roughly 250 px clear at the top and 340 px clear at the bottom. Upload at exactly 1080 × 1920 when you can: a landscape or square image is letterboxed with a blurred background, and anything larger is downscaled. Maximum file sizes are 30 MB for images and 4 GB for video; Stories accept JPG/PNG and MP4/MOV, and a single video Story runs up to 60 seconds before it is split into segments. The image resizer exports the Story size from any image in your browser.

One more rule that saves re-exports: upload at exactly the recommended size or a clean multiple of it. Platforms re-encode everything; giving them an off-ratio file means their crop and their compression decide how your image looks. (What re-encoding does to your video quality, with side-by-side evidence: smartpoststudio.com/video-quality.)
Resizing one visual for eight platforms by hand gets old. Smart Post Studio schedules to all 8 platforms from your desktop — your original file, no cloud re-encoding on the desktop path. Free plan, no card.
