Add Tailor Size Guide as a preferred source on GoogleA size chart shows the numbers. A size recommender makes the decision. Here's how the two differ, which one cuts returns more, and why the best Shopify stores run both.
The Chart
| Factor | Size chart | Size recommender |
|---|---|---|
| Shopper effort | High (read + measure) | Low (answer 3 questions) |
| Output | A table to interpret | One recommended size |
| Returns impact | Moderate | Higher |
| Best for | Reference + trust | Decision + conversion |
| Setup effort | Low | Medium (needs measurements) |
Notes
Why size charts alone leave returns on the table. A chart assumes the shopper will measure themselves accurately and pick the right column. Most don't — they guess, or they "bracket" by ordering two sizes and returning one. The chart is necessary for trust, but it puts the work on the customer.
Why a size recommender moves the needle. By asking a few questions and returning a single recommended size, a recommender removes the guesswork that causes most wrong-size returns. The shopper gets a confident answer, which also lifts conversion because hesitation drops.
The honest answer: run both. Keep the size chart for shoppers who want to verify the numbers themselves, and add a recommender for everyone who'd rather be told. Tools like Tailor Size Guide bundle both in one app, so you don't have to choose — the chart builds trust, the recommender drives the decision.
When a chart is enough. For accessories with little fit variance (scarves, some bags, one-size items), a clean chart is usually all you need. Reserve the recommender for apparel and footwear where fit varies by body.
FAQs
Does a size recommender reduce returns more than a size chart?
Generally yes. A chart relies on the shopper measuring and choosing correctly; a recommender returns one size based on their answers, removing guesswork. That tends to cut wrong-size returns more than a chart alone.
Should I use a size chart or a size recommender?
Use both. The size chart builds trust and serves shoppers who want to verify measurements; the recommender drives the buying decision for everyone else. Many apps include both together.
Can one app do both?
Yes. Tools like Tailor Size Guide combine a size chart and an AI fit recommender in a single Shopify app, so the chart and recommendation share the same measurement data.
When is a size chart on its own enough?
For products with little fit variance — many accessories and one-size items — a clean, accurate size chart is usually sufficient. Add a recommender for apparel and footwear.
