Walmart Swatch Images

What are Walmart swatch images?

A swatch image is a visual preview of a child (variation) SKU within a variant group.

On Walmart, swatch images appear as small thumbnails that represent a specific product variant, typically based on attributes like color, pattern, or finish. They can be found as clickable options on the marketplace’s product page.

When a buyer selects a swatch (e.g., Red), the main listing image automatically updates to reflect that variant, giving them a clearer visual preview before purchasing.

Swatch images are not strictly required, but are highly recommended. Walmart requires them to meet the following criteria:

Square images (100x100 pixels).
Color format: RGB.
File format: JPEG, JPG, PNG, BMP (GIF images aren't permitted).
Clean white or transparent background.

You can set up swatch images for variant listings directly in your Walmart Seller Center using image URLs. These URLs must be permanent, direct links that comply with Walmart’s standards.
