Size spec
Square post size, 1080 × 1080 px
The 1:1 frame for a square feed post. The registry records no crop box for it, so the whole frame is safe.
Kamply is a Mac app that builds posts, reels and store screenshots at these sizes. It works with your Claude Code or Codex subscription.
The frame, drawn to scale.
The boxes are the registry's numbers, placed in the frame's own pixels over a piece the engine made at this size.
Square post
1080 × 1080 px, 1:1
- Padding
- 72 px from every edge
- 936 × 936 px inside
The outer padding. Nothing that carries meaning sits inside it: no text, no button, no logo, no stat. A full-bleed photo or a background wash may cross it. The engine uses 72 px on a 1080 px wide frame and scales that for other widths, snapped to the 8 px grid.
What the engine checks at this size.
A post is not called done until it passes these. Each one is a check the engine runs on the finished post.
Built at the exact pixels
Each frame is an artboard at the registry size at 1x, so the export is the size printed above with no scaling step. Posts export as PNG or PDF.
Text is measured against the boxes
The engine's GRID check measures every text box on the rendered post and fails one that crosses the padding, leaves the safe box or enters a covered margin. Gaps and line heights sit on an 8 px grid. It judges posts whose brief was approved on or after 2026-09-07.
Images are held to web weight
Every image a post embeds is held to 3000 px on its long edge and 4 MB. A PNG with no transparency fails and ships as a JPEG.
No image is stretched past its pixels
An image drawn above 1.25 times its own pixels fails, because it reads soft at feed size. This check judges posts approved on or after 2026-10-05.
Where the numbers come from
Every size Kamply builds to sits in one registry file, and each entry names the platform spec it was read from. This is the source line the registry holds for this size, as written:
