Poshmark listing photo size spec (2026)
Poshmark's photo display has run on a single dimension for years — the 1200 × 1200 square — and in March 2026 it added an optional 900 × 1200 portrait cover. Both render crisply only when your source matches the target; anything smaller than 1200 px gets upscaled and looks soft in the feed. Resizing before upload is the one reliable way to control framing and avoid Poshmark's center auto-crop.
| Spec | Poshmark requirement |
|---|---|
| Classic size | 1200 × 1200 px (1:1) |
| New portrait (2026) | 900 × 1200 px (3:4) |
| Minimum | 500 × 500 px |
| Maximum | 10,000 × 10,000 px |
| Accepted formats | JPG, PNG, HEIC |
| Max file size | ~10 MB per photo |
| Photos per listing | Up to 16 |

Poshmark's 2026 portrait-cover transition explained
On March 25, 2026, Poshmark announced a phased rollout of 3:4 portrait cover photos (approximately 900 × 1200 pixels) across its feed and closet views. Portrait covers show 50% more vertical content and mirror how Poshmark buyers naturally hold their phones.
Critically, existing 1:1 square listings remain fully valid — Poshmark is not deprecating the old format. New listings from 2026 onward can opt into portrait via the "Target size" dropdown above. Many top sellers are A/B testing both formats on fresh listings.

Poshmark photo tips that convert
- Fill all 16 slots. Poshmark allows more photos than any other reseller marketplace — covers, tags, fabric content, flaws, and styling shots all build buyer confidence.
- Match format to category. Square wins for bags, shoes, and jewelry; the new 3:4 portrait wins for dresses, coats, and full-body model shots.
- Shoot above 1200 px, then resize down. Downscaling stays sharp; Poshmark upscaling anything under 1200 px is what causes the blurry-cover complaint.
- Photograph the brand tag and fabric label. Authenticity cues lift conversion and cut "not as described" cases on designer resale.
- Keep a consistent backdrop across your closet. A uniform neutral background makes your feed look like a curated boutique and lifts share-driven traffic.
Frequently asked questions
What's the correct Poshmark photo size in 2026?
Poshmark's long-standing display size is 1200 × 1200 pixels (1:1 square). New in March 2026: a 3:4 portrait option (~900 × 1200). Source: Poshmark Blog — Portrait Photos.
Should I use 1:1 square or 3:4 portrait covers?
Square for handbags, shoes, jewelry, and flat-laid folded garments. Portrait for dresses, coats, jumpsuits, and full-body model shots where vertical detail sells the piece.
Do I need to re-shoot my existing Poshmark closet for the new portrait format?
No. Poshmark is not deprecating the 1:1 square format. Every existing listing continues to display normally. The portrait option is additive, not replacing.
How many photos can a Poshmark listing have?
Up to 16 photos per listing — the highest quota of any reseller marketplace. Listings with all 16 slots filled have measurably higher sell-through.
Why are my Poshmark photos blurry after I upload them?
Almost always because the source was smaller than 1200 pixels — Poshmark upscales to fill the feed card. Upload at exactly 1200 × 1200 for the crispest result.
Does Poshmark auto-crop my photos?
Yes — any non-square (or non-portrait-3:4) upload gets cropped to fit, typically clipping edges. Pre-resize to the exact target format to control framing yourself.
What file formats does Poshmark accept?
Poshmark accepts JPG, PNG, and HEIC up to roughly 10 MB per photo. JPG is the best default.
Can I resize a Poshmark closet header/banner with this tool?
Yes — the closet header is 1200 × 300 (4:1 wide). Select "Custom…" in the Target size dropdown and enter 1200 × 300.
Is this tool free and does it leak my photos anywhere?
100% free, no signup, no watermark, no upload. Every photo is processed locally in your browser via the HTML5 Canvas API.
Can I resize Poshmark photos on my iPhone or Android?
Yes. The UI is fully responsive and every resize runs on-device. Batch downloads arrive as a ZIP via Safari's Files app or Chrome Downloads.
