SizeGuide uses your measurements, wardrobe and available retailer size charts to suggest a clothing size. Coverage and accuracy vary by retailer and product.

The Real Problem
A size 12 at one retailer is a size 8 at another. Brands all use different measurements — and none of them tell you that.
The measurements never change. The labels do.
SizeGuide knows the difference.
The Process
Provide your measurements once. SizeGuide builds your personal sizing profile — securely stored, always yours.
Shop your favourite clothing websites as normal. The extension recognizes product pages where readable sizing information is available; coverage varies.
Get a suggested size using available charts, measurements and confirmed fit evidence. Check the explanation and retailer guide before buying.
See It In Action
Create an account with your email, password, date of birth and country, and accept the terms. Then add a sizing profile — all measurement fields are optional.
Generate a free sizing link and send it to a friend or family member. Once they fill in their measurements, their profile appears in your account — ready for gift shopping.
Add the SizeGuide extension to Chrome in one click. Select your fit preference — fitted, regular, or relaxed — and choose which profile to shop for. That's the setup done.
Browse a clothing product page with readable sizing information. Where supported, SizeGuide suggests a size and provides an explanation, confidence score and any fit notes. Coverage and accuracy vary.
We're building something extraordinary. Using your measurements, SizeGuide will generate a realistic AI model of your exact frame — so you can see precisely how any garment will look on you, before you buy.
Family & Friends Profiles
Finding the perfect gift is hard enough without worrying about whether it'll fit. SizeGuide lets you create sizing profiles for the people closest to you — so every gift lands perfectly.
Send a sizing link. Share a simple link with a friend or family member. They fill in their measurements privately — you never need to ask awkward questions.
Switch profiles instantly. Toggle between your own profile and theirs while you shop. SizeGuide recommends the right size for whoever you're buying for.
Plan a gift. Use a shared sizing profile to inform your choice, and check the retailer's size guide and returns policy before buying.
