Companies Using Sizebay

Fashion stores, mostly in Brazil. 308 of the 457 matched companies are Brazilian, and clothing industries make up 63.41% of matched companies. Lupo, Reserva, Animale and Diesel's Brazilian store loaded it on 14 November 2026, and so did the online stores of Juventus, Inter and Ajax.

Our November 2026 crawl counts 724 domains running Sizebay, after removing 68 that repeated a store already counted, such as Nunalie's and Mark Bellucci's extra country domains. 457 match a company. Since tracking began on 16 March 2026, 95 domains dropped it. Sizebay's own site says more than 1,200 e-commerce stores use its Virtual Fitting Room.

0.46% of Product Customization at TechnologyChecker.io, 15th of 59 rows, on the cleaned 724 domains. Printful leads with 59.5% and Kiwi Sizing is 2nd with 11.77%. The category mixes print-on-demand, product options and sizing tools, so the share compares Sizebay with many tools that do a different job.

Among size and fit tools in our crawl, Kiwi Sizing has 18,568 domains, Volumental 5,004 and Eastside Co Size Matters 3,684. Kiwi Sizing's base is mostly small Shopify fashion stores, while Sizebay's is Brazilian and spans several store platforms. Sizebay also offers a virtual try-on that shows the garment on the shopper's own photo.

Brazil leads with 308 of the 457 matched companies, two in three, then Italy (40), the United States (20), Spain (17) and the Netherlands (10). Italy's rows include the stores of Juventus, Inter, Atalanta and Venezia. Spanish-speaking Latin America is small: Chile 7, Colombia 4 and Argentina 3.

Mostly small fashion brands with a mid-market tail. 40.33% of matched companies with a known size have 1 to 10 employees and 26.18% have 11 to 50. 20.05% have 51 to 200, and 57 companies have more than 200, among them Lupo, Torra, Reserva and Diesel.

Mostly founded since 2000: 32.16% in the 2010s, 18.43% in the 2000s and 11.76% in the 2020s, out of 255 matched companies with a founding year. The older 37.65% include textile makers such as Lupo, founded in 1921 per its LinkedIn data.

On our data: a Brazilian fashion brand with 1 to 50 staff, founded in the 2010s, selling clothing through its own online store with Google Tag Manager, Google Analytics and Facebook Pixel installed, often behind Cloudflare. A second, smaller profile is European football clubs' kit stores.

It recommends a size for each product a shopper looks at. Sizebay's site describes a size advisor, a virtual try-on that shows the garment on the shopper's own photo, and a Fashion Hub of other tools for fashion stores. It covers apparel, footwear and intimates, and says it has helped online fashion retailers since 2014.

Per Sizebay's Virtual Fitting Room page, the shopper enters height, weight and age, then confirms or adjusts how weight is distributed on the body. The tool returns a size for that specific product and shows how the other sizes would fit. For footwear it compares foot shape with the shopper's sizes in other brands.

Sizebay doesn't publish prices. Its site asks stores to schedule a demo, and we found no pricing page when we checked on 14 November 2026. For context, 40.33% of the matched companies running it have 1 to 10 employees, so it isn't limited to large retailers.

Look in the page's network requests for a script from static.sizebay.technology, usually prescript.js inside a numbered folder that identifies the store, such as /6577/prescript.js. Some stores also call vfr-v3-production.sizebay.technology. One WooCommerce store in our sample loaded it through its theme plugin's own sizebay.js instead.
