Which measurement type should I choose when setting up a size recommendation
When creating size recommendations, you need to choose the correct measurement type based on how your size chart is structured. This determines how the system processes customer measurements and matches them to your sizing data.
The three measurement types handle the relationship between customer body measurements and your size chart differently.
1. Body measurements
Choose this option if the numbers in your size chart represent body measurements.
- Customers measure their own body (e.g., chest, waist, hips).
- The app compares those measurements directly against the chart values to suggest a size.
Example:
- Size chart says Chest 92–96 cm = Size M.
- Customer enters chest = 94 cm.
- System recommends Size M.
2. Product measurements
Choose this option if the numbers in your size chart represent the product’s measurements (not the body).
- Product measurements are usually larger than the body to allow for comfort and fit.
- This extra allowance is called extra room and varies depending on the manufacturer.
- If you don’t know the exact extra room, you can use our sample reference chart.
- The app will automatically add this extra room to the customer’s body measurement before comparing it with the product size chart.
Example:
- Jacket size chart (Product measurement): Chest 100 cm = Size M.
- Manufacturer adds 4 cm “extra room” for comfort.
- Customer’s body chest = 96 cm.
- System adds 4 cm → 100 cm → matches chart → recommends Size M.
3. None
Choose this option if you don’t sell apparel but still use sizing (e.g., helmets, shoes, accessories).
- Works the same as Body measurements:
- Customer enters a number.
- System compares it directly with the chart values.
Example:
- Helmet chart: Head circumference 56–58 cm = Size M.
- Customer enters 57 cm.
- System recommends Size M.
How to determine your chart type
Questions to ask yourself
1. What do the numbers in my size chart represent?
- Body measurements customers should have = Body Measurements
- Physical garment dimensions = Product Measurements
- Non-clothing item measurements = None
2. Do I sell clothing?
- Yes, and chart shows body measurements = Body Measurements
- Yes, and chart shows garment measurements = Product Measurements
- No = None
3. How do customers currently use my size chart?
- They measure themselves and find matching numbers = Body Measurements
- They measure themselves but have to “add room” mentally = Product Measurements
Common mistakes
- Using Body Measurements for garment-measured charts: Results in recommendations that are too large because the system doesn’t account for ease.
- Using Product Measurements for body-measured charts: Results in recommendations that are too small because the system adds unnecessary ease.
When in doubt
If you’re unsure about your chart type:
- Look at your current size guide: How do you tell customers to use it?
- Check your returns: Are customers getting items too big or too small?
- Start with body measurements: It’s the most straightforward option for testing
Remember, you can change the measurement type anytime if you find your recommendations aren’t accurate. The key is matching how your size chart is structured with how the system processes customer inputs.
Wrap-up
Selecting the correct measurement type ensures accurate and reliable size suggestions:
- Body measurements → when chart values = body sizes.
- Product measurements → when chart values = garment dimensions (with extra room added).
- None → for non-apparel products with size rules similar to body measurements.
This helps customers trust your recommendations, reduces confusion, and lowers return rates.
