Poshmark photo size: portrait covers, and what to do about your old listings

Cover photos moved from square to 3:4 portrait in March 2026. New listings should be shot and cropped for the taller frame — but your existing square listings need no work at all, and this page explains why.

Your photos are processed on your own device and are never uploaded to a server.

Poshmark photo specifications

Mobile feed

Almost every view is a phone-sized card in a scrolling feed. Past roughly 1200px you are adding upload time, not clarity — framing matters far more than pixels.

2 sizes worth having

  • 900 × 12003:4

    Portrait. Poshmark's current cover format. It states the 3:4 ratio but not a pixel count, so these are our conservative dimensions for it.

  • 1200 × 12001:1

    Square (legacy). Still perfectly valid — Poshmark did not deprecate square, and this is the shape Mercari, eBay and Depop want. Pick this if you cross-list.

What the 3:4 change asks of you, in three cases

Most coverage of this change describes the new ratio and stops, which leaves the only question a working seller actually has unanswered: is there a job here, and how big is it? There are three situations and the answer is different in each.

Listings already live

Do nothing

Poshmark keeps your original upload. A shopper who taps the listing sees the whole square photo exactly as before; only the feed and search cards are framed taller. There is no penalty, no flag and no ranking effect, so re-cropping hundreds of old covers is a weekend spent on nothing.

Listings you are about to post

Shoot for portrait

A 3:4 frame is taller than it is wide, which suits clothing on a hanger or a model far better than square ever did — you get the full garment without the empty floor either side. Frame with a little room at the top and bottom rather than filling the frame edge to edge, and the crop will never clip a hem or a collar.

Photos you cross-list elsewhere

Shoot wide, crop twice

Mercari, eBay and Depop all want square. Rather than reshooting, frame loosely enough that both crops work, then run the same photos through the resizer twice — once at 900 × 1200 for Poshmark and once at 1200 × 1200 for everywhere else. Two ZIPs, one shoot.

One more thing worth knowing before you re-shoot a whole closet on the strength of a product update: Poshmark ran this same experiment once before and reversed it after sellers pushed back. That is not a reason to ignore the current format — it is a reason to spend your effort on new listings rather than on rebuilding the old ones.

Cropping a square photo into a taller frame

Going from square to 3:4 means one of two things has to happen, and it is worth understanding which you are choosing, because the resizer asks.

Fill

Scales your photo until it covers the whole frame and trims what hangs over the edges. Nothing is padded and nothing looks pasted on, but a square photo losing its sides loses roughly a quarter of its width — so anything close to the left or right edge goes.

The right choice for almost every listing photo. Set the focal point on the item and the trim comes off the background.

Fit

Scales the whole photo down until it sits inside the frame and pads the gap with plain white. Nothing is ever clipped, which is why it exists — but on a portrait frame it leaves visible bands above and below your item.

Worth it when the photo genuinely cannot lose an edge: a full-length coat, a set laid out flat, a size label photographed corner to corner.

The one thing to get right in the camera

No crop can invent the top of a jacket that was never photographed. If you know a photo is heading for a portrait cover, take one step back before you shoot — a little unused space around the item is free, and it is the difference between choosing your crop and accepting the one you are left with. Poshmark's own guidance on portrait Covershots makes the same point in more words.

Poshmark rules and details worth knowing

Dimensions are the easy part. These are the things a listing actually gets penalised for, inPoshmark's own words wherever it has published them.

Where these numbers came from

Guides on this topic contradict each other, and several of the most-copied figures are simply wrong. So every claim here carries its provenance, split in two — because the pixel guidance and the hard limits genuinely do not come from the same quality of source.

Where two credible sources disagree on a limit, we take the lower number: preparing 12 photos for a marketplace that accepts 20 costs you nothing, and preparing 20 for one that accepts 12 wastes work at the point of listing.

Common questions

What size should Poshmark photos be in 2026?
900 × 1200 pixels, a 3:4 portrait frame. Poshmark publishes the ratio rather than a pixel count, so that figure is our conservative reading of it — anything at or above 1200px on the long edge is comfortably more than a phone-sized feed card needs. Photos beyond about 2000px buy you upload time and nothing else.
Do I need to re-crop my old square Poshmark listings?
No. Poshmark keeps your original image and shows it in full when a shopper taps into the listing — only the feed and search thumbnails are framed to portrait. Re-cropping a closet of old covers is optional housekeeping, not a fix, and it is not where your time pays off. Shoot new listings for portrait and leave the back catalogue alone.
Is square still allowed on Poshmark?
Yes. Poshmark did not deprecate square, and square uploads work normally — they are simply framed into portrait in the feed. It is also worth knowing that Poshmark trialled this exact change once before and reversed it after seller pushback, so square remains a defensible choice, particularly if the same photos go to Mercari, eBay or Depop.
How many photos can a Poshmark listing have?
16, per Poshmark's own listing guide. Use them: the cover sells the tap, and the rest sell the item. Front, back, label, fabric close-up, and one honest photograph of every flaw.
Why do my Poshmark photos upload sideways?
Because your phone stored the photo in its sensor's orientation and wrote a separate EXIF tag saying which way up it goes. Poshmark reads that tag, rotates the photo, and then discards the metadata — so a tool that strips EXIF without first baking the rotation into the pixels hands Poshmark a photo with no tag and no clue. The resizer on this page bakes the rotation in before it touches anything else.
Does Poshmark have a file size limit?
None that Poshmark publishes, which is why this page does not quote one. In practice a 2 to 3 MB JPEG at portrait dimensions uploads quickly on a phone connection and looks identical to a 12 MB original at the size it is displayed. If your photos are straight off a modern camera, compressing them is the difference between an upload that finishes and one you abandon.
Are my photos uploaded anywhere when I use this resizer?
No. Cropping and encoding happen inside this browser tab using the image machinery your browser already has, and there is no server to send a photo to. You can verify rather than trust: open your browser's network inspector, resize a batch, and watch that nothing leaves.
