3DLOOK vs Bold Metrics

3DLOOK vs Bold Metrics is a choice between measuring a body from photos and predicting it from answers. 3DLOOK asks the person for two phone photos and returns body measurements, while Bold Metrics asks a shopper four to six simple questions and predicts fit with no photos at all.

That difference shapes who each one suits. A made-to-measure brand that needs real measurements leans toward a scan, and a ready-to-wear store that wants a fast size answer leans toward a questionnaire.

How does 3DLOOK measure a body?

3DLOOK measures the person from photos. On the Mobile Tailor page, the person opens a scanning link, then takes a front photo and a side photo with voice guidance.

The page says users should wear fitted clothing, such as leggings and a fitted top. It also says existing photos can't be uploaded, because the scan must run through 3DLOOK's own link.

What does the 3DLOOK scan return?

The Mobile Tailor page describes a 3D body model plus "over 80" body measurements in one section and "over 85 measurements" in another. That level of detail is aimed at people who cut and sew to the body.

The page lists made-to-measure brands, uniform makers, custom apparel, and bridal and tuxedo businesses as its audience. Scan links can go out by SMS or email, sit on a website as a widget, or appear as a QR code in a store.

Where does health and fitness fit in?

The 3DLOOK homepage now leads with FitXpress, which it describes as body data for health and fitness. Its use cases include telehealth, connected fitness and life insurance underwriting.

For a fashion buyer, this matters for one reason. Ask the sales team which product and roadmap your account would sit on, so you know the fashion side gets attention.

How does Bold Metrics predict fit?

Bold Metrics predicts the body instead of measuring it. Its homepage says shoppers answer "4 – 6 simple shopper inputs", such as height, weight, age, pant waist, fit preference, bra band and cup size.

The site says no photos, scans or tape measures are needed. From those answers, it builds what it calls a digital twin of "50+" body measurements and returns a best-fit size for each style.

What does the shopper see?

The shopper gets a recommended size plus a fit rating, such as "Slightly Snug" or "Just Right". They can also see how the other sizes would fit, which helps people who like a looser or tighter cut.

Which Bold Metrics products would a store use?

The homepage names five products:

1. Smart Size Chart: a ready-to-install size tool for product pages.
2. Virtual Sizer: an API for profiles, product finders and personal landing pages.
3. Virtual Tailor: tailor-level body measurements for custom clothiers.
4. Apparel Insights: body, purchase and returns data for design and operations teams.
5. Agentic Sizing Protocol: sizing for AI shopping agents.

Which one suits your business?

Start with what you make and what you need from the shopper. The table below matches common store types to the method that fits.

Your business	Better fit	Why
Made-to-measure suits or bridal	3DLOOK	You need many real measurements, not a size label
Uniform supplier fitting staff remotely	3DLOOK	Scan links can be sent by email or SMS
Ready-to-wear brand with many styles	Bold Metrics	Shoppers answer a few questions and get a size per style
Store worried about photo friction	Bold Metrics	No photos are needed
Team selling through AI shopping agents	Bold Metrics	It names a protocol for agents

What questions should you ask both vendors?

Use the same list on every sales call so the answers are easy to compare:

• What does the shopper have to do, step by step, and how long does it take?
• Does the size come from my own size chart or from your model of my products?
• What do I need to send you before launch: charts, garment specs or past orders?
• Which platforms do you support, and who installs it?
• How is pricing worked out: per scan, per order or per month?
• Where is shopper data stored, and for how long?

How should you test them before you commit?

Run the same small test with each vendor, so you compare like with like:

1. Pick three products that cause the most fit questions, such as a fitted blazer, slim jeans and a stretch dress.
2. Ask five staff members of different builds to get a size from each tool.
3. Have each person try on the suggested size and note whether it fits, runs tight or runs loose.
4. Write down how long each tool took, from first tap to size answer.

A short test like this shows you both accuracy and effort, which a demo video can't.

If neither tool feels right, our guide to other 3DLOOK alternatives lists more options by store size.

What are the tradeoffs of each approach?

Neither method is better in every case. Each one trades effort for detail in a different way.

Photo scans give real measurements of the person in front of the camera. The cost is effort: the shopper must find space, wear fitted clothes and take two photos. Some shoppers will stop halfway.

Answer-based prediction is quick and private, because no photo is taken. The cost is that the measurements are an estimate built from a few answers. A shopper with an unusual build may get a less accurate result.

How does that play out on a product page?

Picture a shopper looking at a $90 pair of chinos. With a questionnaire, they type height, weight, age and waist size, then see "32, Just Right" a few seconds later.

With a photo scan, they would need to step back, prop up the phone and take two photos. That makes sense for a tailored suit, and it can feel like a lot for a single pair of chinos.

Where does ZeDaq.ai fit between them?

ZeDaq.ai sits between the two methods. Its AI size recommendation for fashion stores uses a 30-second scan with one photo plus the shopper's height, which is less effort than two fitted-clothing photos.

The measurements are matched to your own size chart. You enter one chart per garment type, such as tops, outerwear, dresses and bottoms, and the shopper sees your labels. If you haven't added a chart, a generic UK, US, EU or AU chart is used instead.

ZeDaq.ai also adds AI virtual try-on, so the shopper uploads one photo and sees your real garment on their body. It installs as a Shopify app, or as a script-tag widget on WooCommerce, Wix, Squarespace, BigCommerce and custom sites.

Pricing is public. The Free plan is $0 and includes 3 try-ons, 3 measurements and 5 invoices a month. Paid plans are Micro at $14, Starter at $49, Growth at $129 and Scale at $299 a month, each with a 3-day free trial and no card required. Details are on the ZeDaq.ai pricing page.

FAQs

Does Bold Metrics need a photo from the shopper?

No. Bold Metrics' site says it works from a few shopper inputs, such as height, weight and age, with no photos or scans.

Can shoppers upload an old photo to 3DLOOK?

No, according to its Mobile Tailor page. The scan has to run through 3DLOOK's own scanning link with fresh front and side photos.

Do 3DLOOK or Bold Metrics publish their prices?

Neither showed prices on the pages we checked in November 2026. 3DLOOK offers a 7-day trial of Mobile Tailor, and Bold Metrics asks you to request a demo.

Which is better for made-to-measure clothing?

3DLOOK's Mobile Tailor is built for made-to-measure, uniforms and bridal, with many measurements per scan. Bold Metrics also lists Virtual Tailor for custom clothiers, so ask both for sample output.
