Bold Metrics sells AI sizing to brands like New Balance, Canada Goose, Charles Tyrwhitt and Helly Hansen. Its approach is to create "a unique digital twin for each shopper, mapping over 50 individual body measurements" from a short set of questions, with "no scanning, photos, or measuring tapes". On 24 March 2026 it launched the Agentic Sizing Protocol with Gap as launch partner, so an AI shopping agent can ask a few questions and return a size. Garu builds the shopper's body from one photo, matches it to your chart and renders the garment. Bold Metrics facts come from boldmetrics.com and the Gap announcement 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 Bold Metrics if you are an enterprise brand that wants sizing without asking the shopper for a photo, has product data to feed a digital-twin model, and is planning for agentic checkout now. The Gap partnership is real and early.
Choose Garu if you want the shopper to see the garment on their own body and get a size from a photo of it, on Shopify, self-serve, at a published price. Bold Metrics does not offer visual try-on and does not publish pricing or a Shopify listing.

Where Bold Metrics is genuinely ahead
- No photo required. A questionnaire converts where a photo upload might not, especially on a first visit.
- Agentic sizing. A published protocol with Gap for sizing inside AI agents. Garu's sizing runs as a service behind the widget but has no public agent protocol yet.
- Scale and logos. "250+ million Digital Twins" and a wall of enterprise customers.
Where Garu is built differently
- The body comes from a photo. Chest, waist and inseam estimated from the shopper as they are, not inferred from height, weight and age.
- The shopper sees the fit. A render, front and back, next to the size. A twin the shopper cannot see is a number.
- Every size rendered on Plus. The shopper compares the M and the L on their own body.
- Self-serve on Shopify. Free tier, price on the page, live in an afternoon.
The honest decision rule
If a photo is a step you do not want to ask for and your roadmap is agentic checkout at Gap's scale, Bold Metrics is built for that. If the shopper's doubt is visual as well as numerical, Garu answers both from one photo, and you can test it on your own catalogue today.
