Replacing a static size chart with an interactive 'Find My Size' tool lifted conversion rate by 8.0% and revenue per user by 10.0% on Oceansapart's product pages. DRIP Agency ran this test for the activewear brand and published it as a case study. The tool, Sizekick, gives each shopper a size recommendation instead of a generic table to read.

## Result

**+8% conversion rate**

- Conversion rate: +8.0%. More visitors to the product page went on to buy.
- Revenue per user: +10.0%. Revenue grew a little faster than orders, which hints at bigger or pricier baskets.
- Sample size, duration and confidence level were not shared.

## Control

The product page offered a standard static size chart. Shoppers had to read the table and work out their own size.

## Variant

A 'Find My Size' link opened Sizekick, an interactive tool that recommends a size. The rest of the page stayed the same.

## Why it likely won (our reading)

- Fit is a big worry when buying activewear online. DRIP's research ranked fit and size confidence as a top purchase driver for this brand.
- A personal answer takes less effort than reading a size table and comparing it with your own measurements.
- A tailored size can feel more trustworthy than a guess, so fewer shoppers leave to think it over.

## Caveats

Significance, sample size and test length were not shared. The numbers come from the agency's own case study.

## How to run this test

- Hypothesis: If we replace the static size chart with an interactive size recommendation tool, then more shoppers will buy because they feel sure the item will fit.
- Primary metric: Conversion rate on product pages
- Guardrail: Return rate for wrong size
- Guardrail: Revenue per user
- Guardrail: Page load speed on mobile
- Who should test it: Apparel and footwear stores where fit decides the sale and size-related returns are common. It matters less for one-size or loose-fit products, or where shoppers already know their size from past orders.
