Why TellMySize Is Better Than Brand Size Charts
Brand size charts only tell part of the story - we tell you the rest
Size Varies By Model
Ever bought the same brand of shoes but found they fit differently? Brand size charts give general guidelines, but our users report exact fits for specific models.
Real-World Feedback
Brand size charts don't tell you if items run small, large, or true to size. Our community shares how garments actually fit after wearing them.
Body Type Matters
Standard size charts don't account for different body shapes. We match you with people who have similar proportions for more accurate recommendations.
Brand Consistency Ratings
Some brands have consistent sizing across products, while others vary wildly. We rate brands on consistency so you know when to be extra careful.
The Right Size for All Clothing Brands
Our community has contributed accurate sizing data for popular retailers like Nike, Zara, H&M, Levi's and more
True Fit Reviews from Online Shoppers
Join thousands of shoppers who've eliminated wrong size purchases and returns
"I'm a size M in Old Navy but TellMySize correctly recommended size L for Zara shirts. Saved me from a return. The size differences between these brands are significant and now I know exactly what to order."
"I wear 32x32 jeans in American Eagle but needed 34x32 in Levi's 501s. TellMySize confirmed this was normal - apparently Levi's runs smaller in the waist. This site has saved me so much hassle comparing brand sizes."
"Nike size 9, but Adidas 9.5, and New Balance 8.5? TellMySize helped me sort out the confusing differences between sneaker brands. Now I can shop online without worrying about returns."
