07 | Size Memory
SmartSize Size Memory is a feature of the SmartSize AI Fit Recommender that remembers each customer’s measurements after they complete a quiz. This allows returning customers to receive instant recommendations without retaking the quiz every time they shop.

What is SmartSize Size Memory?
- On the first visit, the customer completes a quiz and receives a size recommendation.
- On future visits, SmartSize automatically reuses stored measurements to recommend sizes on other products—without requiring the customer to retake the quiz.
- This creates a seamless shopping experience and improves conversion.
How Does It Work?
The SmartSize Size Memory process follows four steps:
- Customer completes quiz → SmartSize predicts or retains their measurements.
- Measurements cached locally → They are never shared with SmartSize servers.
- Product comparison → Cached measurements are automatically checked against the product’s size table.
- Size recommendation shown → The best size is displayed instantly.
⚠️ Multi-brand accuracy: Customers may be S in one product and XS in another. This is expected and reflects normal brand sizing differences.
Memory Duration and Reset
- SmartSize automatically resets memory after 3 months from the first quiz completion.
- After reset, customers are prompted to retake the quiz.
- This prevents inaccurate recommendations in case of weight or body changes.
- The reset has no impact on pricing or quota consumption.
Does It Affect Pricing?
No. SmartSize Size Memory does not affect pricing:
- Unique monthly users are only counted once per calendar month.
- Returning users who receive recommendations through Size Memory are not counted again within the same month.
- Example:
- January: Customer takes a quiz → counts as 1 user.
- Same customer returns in January and gets a recommendation via Size Memory → does not count again.
- February: Customer returns → counts as 1 user for February.
Across Different Products
When customers navigate to new products after completing a quiz:
- If a product is linked to a SmartSize quiz, the app automatically reuses cached measurements and displays the size recommendation instantly.
- SmartSize compares the stored measurements against that product’s size table to provide the correct recommendation.
- This ensures accuracy across multiple collections and brands.
Link with SmartSize Size Charts
SmartSize Size Memory only works with the AI Fit Recommender.
- SmartSize Size Charts app contains free-format size charts.
- Since free-format charts are not structured data, the matching engine cannot compare cached customer measurements with them.
- Therefore, the two apps are not linked for Size Memory purposes.
