About Sizemaven
Sizemaven tells you which size to buy, then shows real products in that size. Enter a few numbers, such as your room size, your height and weight, your child's foot length or your dog's chest. The tool gives one size, explains the rule behind it, draws it to scale and names the source, such as a maker's own size chart. Under the answer are products on Amazon whose listings confirm that size, within your budget. It is free, with no account, and covers 18 product types.
- Who it is for
- US shoppers buying rugs, beds, curtains, sports gear, kids' shoes, dog crates or rings who are unsure which size to get
- Problem it solves
- A size chart usually stops at the size, and a store usually shows only its own catalog, sized with its own chart.
- The solution
- You enter a few measurements. The tool gives one size, explains the rule behind it and names the source, then lists products on Amazon whose listings confirm that size, within your budget.
- What makes it unique
- It joins the size answer and the products in that size, and each answer names the maker or retailer chart it comes from. It is free, with no account.
