Official and seller guidance commonly prefers listing photos in 4:3 (for example 2700×2025) or 1:1 square format. Etsy search and ads crop images into tight tiles; extreme panoramas or ultra-tall shots lose edges in those crops.

Why? Discovery surfaces assume a predictable frame. When your product sits in the centre third of a wide banner, the square thumbnail may show mostly background. Buyers scroll past before they understand what you sell.

TagPeek treats both 4:3 and 1:1 as pass for aspect-ratio heuristics, and shows product-fill in the 1:1 safe zone on local files and live listings where we can read pixels.

Fix: recompose or export with intentional margins — keep the item inside the centre square even if the master file is 4:3. Our re-upload recipe defaults to 2700×2025 so one export can satisfy ratio guidance and pixel floors together.

Aspect ratio is not the same as resolution. A perfectly square 500×500 file still fails the 635px and 2000px rules. Check all three dimensions on the photo checker.

Third-party blogs disagree on exact pixel sizes; we document the conservative union in rules library and link Etsy Help where wording is authoritative.

搜索方格裁切偏好 4:3 或 1:1；宽图易丢主体。

TagPeek 对 4:3 与 1:1 均视为通过，并提示 1:1 安全区占比。

长宽比与分辨率是两回事，仍需满足 635px 与 2000px。

Is 16:9 allowed?

16:9 可以吗？

Etsy may accept uploads, but search crops may clip a 16:9 hero harder than 4:3 or 1:1 — we flag low product-fill in the square safe zone.

可能能上传，但 16:9 在方格裁切中更易丢主体 —— 我们会提示 1:1 安全区占比偏低。

Should I letterbox to 1:1?

要垫成 1:1 吗？

Many sellers export 4:3 with the product centred so square crops stay clean; pure letterbox bars waste pixels if they push detail outside the safe zone.

常见做法是 4:3 居中构图；纯黑边若把主体挤出安全区反而浪费像素。

Does TagPeek enforce Etsy’s exact crop algorithm?

TagPeek 复刻 Etsy 裁切算法吗？

No. We approximate common grid crops and show fill heuristics you can verify visually.

不会。我们近似常见网格裁切，展示可目视核验的占比启发式。
