ZeDaq.ai vs Bold Metrics: Body Data Sizing Compared

ZeDaq.ai and Bold Metrics both turn body data into a size recommendation, but they collect that data in opposite ways. Bold Metrics predicts body measurements from a few answers such as height, weight and age, with no photo, while ZeDaq.ai measures the shopper from one photo plus their height and adds virtual try-on.

The other big difference is how you buy. Bold Metrics sells through a demo to apparel brands, and ZeDaq.ai is self-serve with public prices. For the wider field of tools you can install yourself, see our roundup of the best AI try-on apps for Shopify.

Disclosure: ZeDaq.ai is our product. Every fact about Bold Metrics below comes from Bold Metrics' homepage, checked November 2026. Confirm details with their team before you decide.

How does Bold Metrics build a size recommendation?

Bold Metrics describes its approach as body data. The shopper gives 4 to 6 inputs, with examples on its site including height, weight, age, pant waist, fit preference, bra band and cup size, per the Bold Metrics homepage.

From those answers, it builds what it calls a "digital twin" and works out more than 50 body measurements. It then matches those measurements against the brand's garment data to suggest a size for each style, based on how the shopper likes clothes to fit.

The site states that no scanning, photos or measuring tapes are needed. For shoppers who don't want to take a photo, that is a real advantage.

What products does Bold Metrics list?

Its homepage lists five products:

• Smart Size Chart: a ready-to-install sizing tool that shows fit across key measurement points on the product page.
• Virtual Sizer: an API for shopper profiles, product finders and personalized landing pages.
• Virtual Tailor: tailor-level body measurements for custom clothiers and made-to-measure brands.
• Apparel Insights: body, purchase and returns data for design, operations and distribution.
• Agentic Sizing Protocol: fit and sizing recommendations for AI shopping agents.

The site lists categories such as athleisure, dresses, formalwear, kidswear and workwear or uniforms. It also reports scale figures, including "300M+" digital twins, on its homepage.

How does ZeDaq.ai build a size recommendation?

ZeDaq.ai measures instead of predicting from answers. The shopper taps "Find my size" on the product page, uploads one full-length photo and enters their height. The scan takes about 30 seconds.

The measurements are then matched to the size chart you enter yourself, one chart per garment type: tops, outerwear, dresses and bottoms. The shopper sees one label from your chart. If they fall between sizes, the tool sizes up to cover the largest relevant measurement. If you haven't added a chart, it falls back to a generic UK, US, EU or AU chart.

The same widget offers AI virtual try-on. The shopper uploads a photo and sees your real garment on their body. For how photo-based measuring works under the hood, read our explainer on how AI estimates measurements from photos.

Where do the two approaches really differ?

Shopper effort

Bold Metrics asks a few questions. ZeDaq.ai asks for one photo and a height. Some shoppers prefer typing answers, and others find a photo faster than guessing their own pant waist. Test both with your own customers.

Where the size data comes from

Bold Metrics matches to garment data the brand supplies. ZeDaq.ai matches to the body-measurement size chart you enter. If you already have detailed garment specs, ask Bold Metrics how they import them. If you only have a standard size guide, ZeDaq.ai can use it as is.

What else comes with it

Bold Metrics pairs sizing with merchandising data and an agent-facing protocol. ZeDaq.ai pairs sizing with virtual try-on, live-camera eyewear try-on and tools for tailors.

How you buy

Bold Metrics lists no prices and asks you to request a demo. ZeDaq.ai lists prices and you can start without talking to anyone.

Which one suits your business?

Use this checklist to decide which to shortlist.

• Do you already keep detailed garment specs? Bold Metrics matches shoppers against the brand's garment data.
• Do you want shoppers to avoid photos entirely? Bold Metrics says it needs none.
• Do you want try-on and sizing in one widget? ZeDaq.ai combines them.
• Do you need to launch this week without a sales call? ZeDaq.ai is self-serve.
• Do you sell on Shopify, WooCommerce, Wix or a custom site? ZeDaq.ai has a Shopify app and a script tag for the others. Ask Bold Metrics which platforms they support, since its homepage doesn't name any.
• Do you make garments to measure? Compare Bold Metrics' Virtual Tailor with ZeDaq.ai's measurement links for tailors.

If you're weighing other photo-based tools too, our comparison of ZeDaq.ai and 3DLOOK covers another scanning approach. For a chart-led widget, see Easysize or ZeDaq.ai.

How do the costs compare?

Bold Metrics doesn't publish pricing on its homepage. Expect to request a demo and receive a quote.

ZeDaq.ai lists its prices publicly:

Plan	Price
Free	$0 (3 try-ons, 3 measurements and 5 invoices a month)
Micro	$14/mo
Starter	$49/mo
Growth	$129/mo
Scale	$299/mo

Every paid plan has a 3-day free trial with no card required. Each size scan uses one measurement from your plan.

How should you run a fair test?

If you can, test both on the same products. Here is a simple method.

1. Pick three styles that cause the most fit questions in your store.
2. Recruit five people of different heights and builds who know their size in those styles.
3. Run each tool and note the suggested size for each person and style.
4. Compare with reality. Have each person try the garment on and record whether the suggestion was right.
5. Note the effort. Ask testers which flow felt quicker and which they trusted more.

A small test like this tells you more than any vendor claim, including ours.

What should you ask each vendor before you commit?

Bring the same questions to both, so you can compare answers side by side.

Questions for Bold Metrics

Questions for ZeDaq.ai

Questions to ask yourself

• Will our shoppers be comfortable taking a photo, or would they rather answer questions?
• Do we have someone to run an integration project, or do we need self-serve?

Write the answers in a shared document. The right choice usually becomes clear once both sets of answers sit next to each other.

FAQs

Does Bold Metrics need a photo?

No. Its homepage says no scanning, photos or measuring tapes are needed. The shopper answers 4 to 6 questions instead.

Does Bold Metrics offer virtual try-on?

Its homepage, checked November 2026, doesn't list virtual try-on. Ask their team if you need it.

Bold Metrics lists Virtual Tailor for custom clothiers. ZeDaq.ai offers tailor tools with measurement links, a client CRM, orders and invoicing. Compare both against how your workshop runs.
