Virtusize is a Tokyo-headquartered fit platform with offices in Seoul and Shanghai, used by 500-plus brands including Adidas, Levi's, Under Armour, Ralph Lauren and AllSaints. It builds recommendations from "250,000+ fit profiles" and sells a visual size table and a data product alongside. Garu is a Shopify app that estimates the shopper's measurements from one photo, matches them to your chart and renders the garment. Virtusize facts come from virtusize.com and the Shopify App Store on September 21, 2026.
We make Garu, so read accordingly. Where the other side is ahead, this page says so plainly.
The short answer
Choose Virtusize if you sell in Japan, Korea or China, want a vendor with a large Asia-Pacific base and 500-plus brand references, and want a fit recommender with integrations across Shopify, Magento, Salesforce Commerce Cloud and headless setups.
Choose Garu if you want the shopper to see the garment on themselves as well as get a size, from a photo, on Shopify, with a price on the page. On September 21, 2026 Virtusize's Shopify App Store page said the app "is not currently available", although its own site quotes Shopify pricing of $1 for the first month, then from $39.

Where Virtusize is genuinely ahead
- Brand base. 500-plus brands and case studies such as Under Armour's "27.0% return rate reduction, year-on-year".
- Markets. Thirty-plus markets with a native presence in Japan, Korea and China. Garu's merchants are in the US and Europe.
- Platform reach. Magento, Salesforce, BigCommerce, WooCommerce and headless, not only Shopify.
Where Garu is built differently
- The shopper sees the garment on their body. Rendered, front and back. Virtusize's site names virtual try-on but its product pages describe fit recommendations and size tables.
- Measurements from a photo, today. No profile to build, nothing to go stale.
- A live Shopify listing. Install, free tier, published tiers.
- Every size rendered on Plus.
The honest decision rule
If your growth is in Asia-Pacific and you want the vendor with the deepest base there, Virtusize is that vendor. If you are on Shopify and the shopper's question is how it looks and which size, Garu answers both from one photo, and you can install it today.
