It depends on the product category. For furniture and home decor, include height, width, depth, and seat height. For bags, show strap drop, overall height, width, and base width. For apparel, use chest, waist, length, and sleeve. For electronics, length, width, and thickness. Weight is a useful addition for any product where shipping or handling matters. Amazon recommends showing both inches and centimeters for international buyers.

Yes — and they're strongly recommended. Amazon explicitly allows graphics and text on secondary images (positions 2–7), and top sellers consistently use dimension infographics to reduce returns and lift conversions. Shopify, Etsy, Flipkart, and most other major platforms support annotated secondary images. Note that your main listing image must be a clean product shot — dimension infographics go in the supporting image slots.

Blend uses AI to detect your product's position in the image, then places measurement arrows, ruler graphics, and dimension labels based on the values you enter. There's no manual dragging or aligning — just upload your photo, type your measurements, and download the finished infographic. The AI handles layout, spacing, and formatting so the result looks professionally designed.

Blend works across all major product categories — furniture, home decor, bags and luggage, electronics, apparel, kitchenware, toys, tools, sporting goods, and more. Any product where size affects a buyer's purchase decision benefits from a dimension infographic, which is why it's one of the most-used secondary image formats across Amazon and Shopify stores worldwide.
