How to check pinterest pin size?

Enter the pin's width and height in pixels and run the tool. It reduces them to a W:H ratio (e.g. 1000×1500 → 2:3) and tells you if the size is feed-safe. If it is off-spec, resize to the 2:3 best-practice size of 1000 × 1500 px.

How does a pinterest pin size checker work?

It does deterministic math: your dimensions are reduced to their simplest ratio using the greatest common divisor, then the aspect ratio is compared against known best-practice formats (2:3, 1:1, 9:16, 1:2.1). No AI is involved and it does not fetch or inspect your actual Pinterest pins — it only evaluates the numbers you type.

Pinterest Pin Size Checker

What is Pinterest pin size checker?

Pinterest Pin Ratio Checker — Check your pin size before you post: enter the width and height in pixels to verify the ideal 2:3 best-practice ratio and feed safety instantly.

Your pixel dimensions are rounded and reduced to a W:H ratio using greatest-common-divisor (GCD) arithmetic. The aspect ratio is then compared against a fixed threshold table: within ±0.04 of 2:3, 1:1, or 9:16 matches that format; taller than 2:3 (down to ~1:2.1) counts as a long pin; anything else is off-spec. Verdicts are feed-safe for 2:3 and 9:16, low-visibility for square 1:1, and cropped-in-feed for long or off-spec sizes. The 2:3 "ideal pin" size is widely documented creator guidance — this tool does not claim Pinterest endorses it and it does not check real pins, only the numbers you enter.

Good to know

The 2:3 "ideal pin" size is widely documented creator best practice, not an official Pinterest requirement — the tool never claims platform endorsement.
The tool checks the numbers you enter only; it cannot inspect real pins or your Pinterest account.
Non-integer dimensions are rounded before the ratio is computed, so borderline sizes may match a different format than the unrounded value would.

How it works

Your pixel dimensions are rounded and reduced to a W:H ratio using greatest-common-divisor (GCD) arithmetic. The aspect ratio is then compared against a fixed threshold table: within ±0.04 of 2:3, 1:1, or 9:16 matches that format; taller than 2:3 (down to ~1:2.1) counts as a long pin; anything else is off-spec. Verdicts are feed-safe for 2:3 and 9:16, low-visibility for square 1:1, and cropped-in-feed for long or off-spec sizes. The 2:3 "ideal pin" size is widely documented creator guidance — this tool does not claim Pinterest endorses it and it does not check real pins, only the numbers you enter.

Examples

Ideal pin size

Reduces to 2:3, matches standard-2:3, verdict feed-safe.

Square image

Reduces to 1:1, matches square-1:1, verdict low-visibility — valid but smaller in feeds.

Extremely tall image

Ratio 1:10 is off-spec — the tool warns it will crop heavily.
