Why Pinterest Favors Vertical Pins (and the 2:3 Rule)

Pinterest judges pictures partly by shape. The grid gives every pin the same width and plenty of room for height, so a tall pin simply takes up more screen than a wide one. That mechanical fact explains most of Pinterest's preference for vertical pins, and it comes with concrete numbers: a 2:3 recommendation, a 1:2.1 cutoff, and pixel sizes this article walks through with a real conversion from a blog photo to a standard pin.

Why vertical pins win: the grid's geometry

Fixed width, variable height.

The Pinterest feed is a grid of equal-width columns with flexible height. A wide image scaled to column width sits as a short strip. A 2:3 pin stands roughly twice as tall in the same column. Same content, twice the space, and a bigger target to tap.

None of that is an algorithm secret. It is layout arithmetic. A taller pin is simply harder to scroll past, which makes shape one of the few factors you fully control.

The grid also explains why Pinterest names one preferred shape. Its whole browsing model is the column scroll, and it keeps that working by limiting how much height any one pin can take.

The 2:3 ratio in pixels

1000x1500, and a ceiling.

For every two units of width, three of height. At Pinterest's working size that is 1000x1500, the Pin (Standard) preset in Pinterest Image Resizer. Tall enough to stand out in its column, short enough to show without being cut.

The ceiling is 1:2.1, or 1000x2100. Beyond that, the feed can cut off the lower part of the pin until someone opens it. The Pin (Long) preset stops exactly at that limit for that reason. Taller pins exist, but their endings go unseen.

Text size matters inside that frame. A 1000x1500 pin shown in a column a fraction of that width shrinks your title a lot, so headline type needs to be much larger than it looks on your design screen.

From wide blog photo to standard pin, with numbers

What the crop discards.

Take a 1920x1080 blog photo and the 1000x1500 preset with Crop to fill. Reaching a 0.667 ratio from 1.778 means keeping the full 1080 pixel height and a 720 pixel wide column, discarding about 62 percent of the width. By default that column comes from the centre. Press Adjust crop to drag it onto the subject and zoom if needed, so the pin is built from the slice you choose.

That result is often fine for photography and often a problem for graphics. The alternative is Fit without cropping, which places the whole photo in the tall frame on a solid colour or a blurred copy of itself. For recipe and product pins, where cropping might cut off ingredients or a product edge, fitting is often safer, and a brand-colour background makes the space look intentional.

Better still, compose pin art vertically from the start and let the horizontal version come second.

Idea Pins and the other Pinterest sizes

The supporting cast.

The Idea Pin / Story preset is 1080x1920, the full-screen 9:16 frame shared with Stories and Reels elsewhere, so vertical content made for other apps usually fits directly. The remaining presets are housekeeping: a 1000x1000 square pin for occasional product shots, a 165x165 profile photo, and a 600x600 board cover.

Board covers deserve one design note: they show small and may be trimmed, so treat them like icons. One strong central subject and a consistent palette across covers makes a profile look curated rather than accumulated.

Pin sizing mistakes that bury good content

Shape errors, mostly.

When a solid pin underperforms, the cause is often one of these.

Pinning wide blog photos untouched, so they sit shorter than every vertical neighbour
Building extra-long pins whose call to action sits below the 1:2.1 cut line
Placing titles in the bottom fifth of a long pin, the first area to be cut
Uploading squares out of habit when the same art at 2:3 would take half again as much room
Using Crop to fill on recipe cards and slicing off ingredients listed near the edges

Tips and companion tools for pin production

Design tall, batch the rest.

Design at 1000x1500, keep text in the upper two thirds, and remember that pins circulate for months, so timeless framing lasts longer than dated references. Choose JPG for photo pins and PNG for pins with text overlays or flat graphics. WebP files are smaller, but some scheduling tools do not accept them yet. Download all (ZIP) saves every size with labelled file names.

When volume matters more than tuning each pin, Bulk Image Resizer processes a whole set of images to pin size at once, Crop Image handles a careful manual crop, and Instagram Image Resizer refits the same vertical art for the other portrait-heavy feed. Judge the result in the app too: the real column width on your own phone is the honest test of every design choice.
