Shopify Fit Recommender & Size Recommender
Stop making shoppers guess. Our AI fit recommender asks a few questions and tells each customer their size.
A size chart makes shoppers do the work; a fit recommender does it for them. Tailor Size Guide's AI fit recommender asks each shopper a couple of quick questions — height, weight, usual size, fit preference — and recommends the single size most likely to fit. That removes the guesswork that causes wrong-size returns and the hesitation that loses sales. It installs on Shopify in minutes, no theme code.

Why a fit recommender beats a static chart
Most shoppers won't measure themselves or decode a table — they guess, or they bracket-buy two sizes and return one. A fit recommender gives them one confident answer ("We recommend a Medium"), which is exactly what removes the wrong-size returns and abandoned carts a chart alone can't.
- Recommends one clear size per shopper
- Cuts wrong-size returns and bracketing
- Lifts conversion by removing size anxiety
- Works for first-time and gift buyers who don't know your fit
How the AI size recommender works
It estimates the shopper's body from a few inputs (height, weight, usual size in a known brand, fit preference), then matches that estimate against each product's real measurements and the desired ease. The result is a per-product recommendation — not a generic S/M/L — and it improves over time as you collect post-purchase fit feedback.
- Per-product recommendations from real garment data
- 3–4 quick questions, high completion
- Calibrates to the shopper's usual size
- Learns from "ran small / true / ran large" feedback
Works alongside your size charts and made-to-order
The fit recommender is part of the same app as your size charts and made-to-order capture. The chart builds trust for shoppers who want to verify the numbers; the recommender drives the decision for everyone else; and made-to-measure handles your custom-fit products. One install covers your whole catalog.

Frequently asked questions
What is a fit recommender on Shopify?
It's a tool on your product pages that asks the shopper a few questions — typically height, weight, usual size, and fit preference — and recommends the size most likely to fit, instead of making them read a size chart. Tailor Size Guide includes an AI fit recommender.
How does the AI size recommender decide a size?
It estimates the shopper's body from their inputs, calibrates to their usual size in a known brand, then matches that against each product's real measurements and the desired fit. It returns one per-product recommendation and improves as you collect post-purchase fit feedback.
Does a fit recommender reduce returns?
Yes. Wrong size is the top apparel return reason, and giving each shopper one clear recommended size removes the guesswork and bracketing that cause those returns — so it directly cuts wrong-size returns while lifting conversion.
How do I add a fit recommender to my Shopify store?
Install Tailor Size Guide, enter accurate garment measurements, configure the recommender questions, and place the 'Find my size' button on the product page. No theme code is required.
Is there a free fit recommender for Shopify?
Tailor Size Guide offers a free plan to start. The AI fit recommender and made-to-order capture are available on paid plans.
