Shapewiz · a product by IT BrainA size shoppers can check, right on the product page.

Shapewiz is the Shopify size app we designed, engineered and run. Shoppers type a height and weight, shape their Live Body Twin until it looks like them, and get one size from the store's own chart, with how it fits. Pick a garment from the rail and find your size.

Why clothes come back

Two sizes in the cart means one coming back.

Few shoppers know their hip measurement in centimetres, so they guess, or buy two sizes and return one. Shapewiz starts from what they do know, and the size it suggests travels with the order.

87%of online fashion shoppers name a poor fit as a reason they send clothes back

42%order more than one size to choose from at home

How it fits

Not just a size. How it sits at the bust, the waist and the hips.

Every result reads like a fitting: one size, a line for each area of the body, how sure it is, and the other size when the shopper sits between two. Change the fit to see it move.

Every garment

Sized the way each garment is sold.

An abaya is bought by its length, a kurta's chart is measured flat, a suit has a size per piece. Shapewiz reads each one for what it is. Pick a garment to see the real result.

Where the hem falls on her

For abayas and thobes the length decides the size as much as the body. Shapewiz works out where each size ends on the shopper, at the ankle, on the floor or on the floor in heels, and says it in words.

A chart measured flat, read right

Kurta and shirt charts are usually the garment laid flat. Shapewiz doubles the widths, allows the room the garment needs over the body, and tells him where the length ends, “just below the knee on you”.

Menswear, suits and sets

Men shape the chest and stomach on a men's figure, or start from the trouser size they already know. Suits and sets get a size for every piece, with the reason when the pieces differ.

Why stores pick it

A Fit Finder that starts from your chart, not from a quiz.

Most size apps are a chart in a pop-up or a short quiz. The big sizing platforms sell yearly contracts. Shapewiz sits between them: the shopper's own body, read against the store's own numbers, on a monthly Shopify plan.

Shapewiz compared with the usual kinds of size tools
Question	Shapewiz	Size chart pop-ups	Quiz-style finders	Enterprise platforms
The size comes from	The store's chart, matched to the shopper's body	The shopper reading a table	Answers to a few questions	The vendor's own model
The shopper sees	A figure that changes as they answer	A table	Icons or sliders, usually	Depends on the vendor
How it fits	A line per area, and how sure	Not shown	One size, usually	Often a fit note
Abayas, kurtas, suits	Length, flat charts, a size per piece	As tables	Rarely	Depends on the vendor
How it's paid	Free plan, then flat monthly, no fees per order	Free to low monthly	Monthly, some per order	Yearly contracts

Summarised from Shapewiz's review of 45 size apps and sizing vendors (Shopify App Store listings and vendor websites, read 28 October and 8 November 2026). Each app's own listing has its details.

What is Shapewiz?

A Shopify app built and run by IT Brain for fashion stores. It adds the store's size charts to its product pages and a Fit Finder that turns a shopper's height and weight into one size from that chart, with how it fits at each area.

Do shoppers need a tape measure?

No. Height and weight are enough for a size: Shapewiz's own body model, built on more than 23,000 adults measured with a tape, turns them into a body. Shaping the figure, a bra size, a trouser size or their own measurements make it closer if they want.

Does the size come from Shapewiz or from my chart?

From your chart, always. Shapewiz estimates the shopper's body, then checks it against your numbers, body or garment, flat or all the way round, with the room each garment needs.

Will it slow my product pages?

The script on the product page is about 10 KB. The panel loads only when a shopper taps, and the size is worked out in their browser.

Which languages does it speak?

English, Arabic, Urdu, French, German, Spanish, Italian, Dutch and Turkish, following the store's language on every plan. Arabic and Urdu read right to left.

Where can I install it?

Shapewiz is with Shopify for App Store review. Plans, help and early access are on shapewiz.app.

Can you set our charts up for us?

Yes. On the Pro plan we set up your first 20 charts: send them in any form, a photo, a PDF or a spreadsheet, and we check them against your products.

Is shoppers' data safe?

Shoppers stay anonymous: no account, no name, no email. Their answers stay in their own browser, Shapewiz can't see the store's orders or customers, and its data is deleted when a store uninstalls.

Can you build sizing Shapewiz doesn't cover?

Yes. For made-to-measure, uniforms or unusual ranges we build custom sizing flows and Shopify apps, as we did for a made-to-measure suit configurator.
