Returns Are a Solvable Problem on Shopify
For most apparel stores, the return reduction from a good sizing app pays for the subscription many times over. The challenge isn't whether to add one — it's choosing the right kind, because "reduce returns" apps fall into a few distinct categories that solve different parts of the problem. Here's how they compare.
1. Size Chart Apps
The baseline. These let you build and assign size charts (by product or collection) without editing your theme. Popular options include Kiwi, ESC, and BF Size Charts, many with free tiers.
- Best for: establishing baseline fit information quickly.
- Limit: a chart is information, not a decision — most shoppers don't read it, so chart apps alone only go so far. (More in Size Chart Best Practices.)
2. Fit Quizzes
These ask the shopper a few questions (height, weight, fit preference, how another brand fits) and return a suggested size. Interactive guides and fit quizzes have been reported to cut size-related returns by up to 50%.
- Best for: turning a static chart into a guided answer.
- Limit: accuracy depends on the questions and how well they map to each product.
3. Virtual Try-On / AR
These let shoppers visualize a product on themselves. Stores implementing virtual try-on have reported conversion increases up to 189% and return reductions around 64%.
- Best for: engagement and visualizing look, especially in categories where appearance matters.
- Limit: great for "how it looks," less directly focused on "which size" — fit is the bigger returns driver.
4. AI Size Recommendation
These predict the shopper's best size for a specific product using body inputs and how they fit in other brands. This category targets the exact decision behind most returns — which size fits me?
- Best for: directly cutting size-driven returns and lifting conversion.
- Why it matters: fit and sizing drive 53–70% of apparel returns, so the sizing layer is usually the highest-leverage fix.
How to Choose
- If you have no size guidance: start with a size chart app (baseline trust).
- If shoppers still guess: add a fit quiz or AI size recommendation to make the decision for them.
- If appearance is a big factor (e.g., statement pieces): consider virtual try-on for the visual layer.
For most apparel stores, the sizing/recommendation layer delivers the most return reduction per dollar, because it attacks the leading cause of returns head-on.
Where YourSizer Fits
YourSizer is the size recommendation layer: it gives each shopper a product-specific size answer, working alongside your existing size chart. It's built to reduce size-driven returns and lift conversion at once. See how it works for brands on the for-brands page, or estimate impact with pricing.

Frequently Asked Questions
What kind of Shopify app reduces returns the most?
For apparel, AI size recommendation tends to deliver the most return reduction, because fit and sizing drive the majority of returns — though a size chart app is a sensible baseline.
Do size chart apps alone reduce returns?
Partly. A chart is information, not a decision, and most shoppers don't read it. Pairing it with a fit quiz or size recommendation closes the gap.
How much can these apps cut returns?
Reported results range from up to 50% (fit quizzes) to around 64% (virtual try-on), with AI size recommendation targeting the core size-fit decision directly.
