What is Poshmark?
Poshmark is a social commerce marketplace where users can sell and buy new and second-hand fashion, electronics, and home goods. Most sellers on the platform use it for reselling products.
Poshmark divides the listings into various categories, including:
- Kids
- Men
- Women
- Electronics
- Beauty and Wellness
- Pets
- And many more.
In these categories, buyers can find all kinds of items, such as shoes, accessories, cookware, etc. The platform does not limit the listing of designer items, which makes it a perfect spot to buy products across a variety of price ranges.
Poshmark was founded by Manish Chandra in 2011 and has continued to grow in popularity ever since. In fact, the company managed to generate $2 billion in revenue for sellers in a single year, 2019.
The success of Poshmark is linked to its social selling approach, which is not found in other e-commerce sites. It allows users to follow each other, like listings, share items, leave comments, and more. All these aspects make users spend an average of 23-27 minutes a day on the platform.
Latest Poshmark Image Size and Background Requirements
Out of numerous elements that contribute to selling fast on Poshmark, the one crucial aspect that has the most impact is high-quality product photography with the right image size and a clean background.
Today, 75% of online buyers rely on product photos to make purchase decisions. Similarly, there is a 94% higher conversion rate for high-quality product photos than for low-quality ones. This urges that sellers must know about Poshmark's photo size guidelines, focus on clean backgrounds, and prioritize high-quality shoots to make their listings stand out and convert fast.
The latest Poshmark image size and background requirements are as follows:
Image Size
You should shoot photos in square (1:1) mode. The minimum size accepted is 500 x 500 pixels, while the maximum can go up to 10,000 x 10,000 pixels. The ideal would be 1600 x 1600 pixels.
Poshmark automatically crops uploaded photos to a square ratio (1:1) regardless of original orientation. Therefore, it is better to pre-crop images to a square format to avoid unwanted cropping of important details.
Background
Although there are no specific background requirements, a plain white background is strongly recommended for listing photos. This helps the item pop out and gives a professional vibe. Avoid distracting backgrounds that can detract from the item's visibility.
Photo Quality
Sellers can only add original photos. Stock or copyrighted photos are prohibited. Make sure the photo quality is top-notch with proper lighting, as low-quality photos might lead to listing removal. Also, avoid watermarks and borders around photos.
Tip: insMind AI photo editor lets you easily adjust lighting, change the background, and enhance photo quality with simple clicks.

Inventory Management Apps
Most e-commerce sellers do not rely on just one platform. Cross-posting listings on Poshmark and other platforms like eBay or Mercari saves time and broadens market reach.
If you are cross-selling, you should use Vendoo, List Perfectly, or SellerAider to manage listings across multiple marketplaces. These tools sync inventory across platforms to prevent double-selling and automate relisting tasks.
Bookkeeping Software
QuickBooks, Wave, and GoDaddy Bookkeeping are some useful accounting software to track income, expenses, and tax deductions. They categorize your business expenses and generate financial reports that simplify tax preparation and provide clarity on business profitability.
Receipt Scanners / Apps
It is essential to track sourcing receipts to have a proper understanding of your actual costs. Rather than stuffing paper receipts into drawers, use Expensify, Evernote, or Shoeboxed to digitize and organize all source receipts in one place. Once done, you will have searchable records for deduction documentation and inventory cost tracking.
