Sizes
Image sizes Kamply builds to, with the safe boxes drawn in.
Every size here is read from the registry the Kamply engine builds from, with the box each platform crops or covers. Where a finished piece exists at a size, the boxes are drawn over it.
Sizes with a real render.
Each page below shows a piece the engine made at that exact size for a real product, with the boxes drawn on top to scale.
In the registry, render coming.
Kamply builds to these sizes too, and the numbers are the registry's. No finished piece exists at them yet, so each one gets a page in the list above once it has one.

How each size is checked.
A post is not called done until it passes the engine's checks. These are the ones that concern size.
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.
Crops are stamped from the master
On a crop set the engine's crop tool cuts every banner from the master and stamps it. The FORMAT check fails a crop that is older than its master.
When a platform changes a size
The registry is one file. When a size is missing or a platform changes one, the engine looks up the platform's published spec, adds the entry with a source line naming where the number came from, then builds. It does not guess a size. Each page here prints that source line as the registry holds it. Most are short and carry no check date, and the ones that carry one say so.
For the story, reel and feed boxes with each number's source and date, read Safe zones for reels, stories and feed posts, in pixels.
