Naiz Fit is a Spanish size-advisor platform whose logo wall includes Moschino, Alberta Ferretti, Desigual, Levi's, Kiabi and Parajumpers. It sells a size advisor for ecommerce, a virtual try-on, and a set of fitting and measurement audits for product teams, and integrates with Shopify, Magento and Prestashop. Its parent, the Nasdaq-listed MySize, announced on 14 September 2026 an acquisition-led strategy to build a defense technology platform. Garu estimates measurements from one photo, matches them to your chart and renders the garment. Naiz Fit facts come from naiz.fit 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 Naiz Fit if you are a European brand that wants a size advisor with strong Spanish and Italian references and product-team tooling such as fitting and measurement audits, and you have satisfied yourself about where its parent's investment is going.
Choose Garu if you want a company whose only product is try-on and sizing, a render the shopper can see, measurements from a photo, and a published price on Shopify.

Where Naiz Fit is genuinely ahead
- References. Moschino, Desigual, Levi's, Parajumpers, with case claims such as a "90% reduction in returns" at Parajumpers.
- Product-team tools. Fitting audits, sizing consistency and measurement audits. Garu is a storefront product.
- Platforms. Shopify, Magento and Prestashop plus custom builds.
Where Garu is built differently
- One product, one focus. Garu makes try-on and sizing for product pages, and that is the whole company.
- Measurements from a photo. Naiz Fit's site does not state what the shopper enters; Garu asks for one photo and estimates chest, waist and inseam.
- The render shows fit. Front and back on every plan; every size on Plus.
- Price on the page. Naiz Fit publishes none.
The honest decision rule
If you need Naiz Fit's product-team audits and its European references, it has them. If you want a vendor whose engineering hours are all going into the product on your page, and a picture as well as a number, that is Garu.
