Virtusize gives every shopper a size they're confident in.
They buy. They keep it.






Shoppers abandon cart
When fit confidence is low, shoppers drop off at size selection.
Of returns are size-related
Each costs $30–$40 to process — a cost on every order.
Never come back
First-time buyers rarely return after a poor fit. The silent LTV killer.

Gender, age, height, weight. That’s all Virtusize needs. Four fields, a few seconds — and they’re looking at their ideal fit.

Shoppers don’t just get a size — they see how the garment sits. Measurements are plotted directly onto the item: shoulder, bust, wrist, hip. No more guesswork.

Virtusize matches their profile against 250,000+ real fit profiles to personalise the recommendation. Your shoppers add to cart directly — and they don’t come back to return it.

Shoppers pick a shoe they own and love.
A real-world reference that makes the recommendation feel personal — and the decision feel easy.

Foot width, foot shape — narrow, average or wide; Egyptian, Greek or square. These are the variables that determine whether a shoe is truly comfortable. Standard size charts don’t ask. We do.

Virtusize analyses the shoe’s construction — height, width, front shape — and cross-references it with the shopper’s foot profile and brand sizing data. No more guesswork — just add to cart.

Laptop, water bottle, phone, tablet and more — the everyday items that matter most, all checked against the bag so shoppers know exactly what fits before they commit.

Virtusize maps each item against the bag's exact internal dimensions — width, height, depth. An objective answer to the question every bag shopper is silently asking — doubt removed, purchase made.

Age is just a starting point. Virtusize sizes to the actual child — height, weight, gender — so the right size is always based on who they actually are, not the number on the label.

Parents know their child best. Virtusize shows two or three sizes that work, with honest context for each. The right choice, made with confidence — before it arrives, and before they outgrow it.

Most fit tools rely on body scans or long questionnaires. Virtusize works from what a shopper already knows — their measurements or a garment they already own — and cross-references it with 250,000+ fit profiles. It's faster for the shopper and more accurate because it's grounded in real purchase outcomes, not theoretical body models.
Apparel (tops, bottoms, dresses, outerwear for men, women, unisex), footwear (sneakers, boots, heels, kids), bags, and kids apparel. Each category has its own fit logic — footwear accounts for US/UK/EU/JP sizing standards, bags use volume and proportion mapping, kids apparel includes age-based growth logic.
Any format — CSV, Excel, PDF, a product feed. Our AI automatically normalises your data to the Virtusize standard. You don't reformat anything.
