Size Comparison
Show product scale with everyday objects
Show your product's real-world size by placing it next to a familiar reference -- a hand, coin, ruler, or everyday item. Customers instantly understand the scale without reading dimensions.
How Size Comparison Works
Size Comparison uses AI to composite your product image next to a universally recognized reference object, giving customers an instant understanding of physical scale. The AI correctly sizes and positions the reference item (a hand, coin, credit card, ruler, or everyday object like a coffee mug) relative to your product dimensions, then renders the comparison with consistent lighting and perspective.
This tool directly addresses one of the top reasons for e-commerce returns: unexpected product size. When customers see a product next to a hand or a coin, they immediately understand the scale without reading dimension specifications. Jewelry sellers, electronics retailers, and home goods brands see the most benefit, but any product listing improves with a scale reference.
For the most accurate comparison, photograph your product with a real reference object nearby (even partially in frame) so the AI can gauge actual size. If that is not possible, the AI estimates size from context clues. Simple product shapes (rectangular, cylindrical) produce the most convincing size comparisons. Each image costs $0.025.
