Real Shopify Stores. Real Sizing Results.
Merchants share what changed after they added size charts and size recommendations to their product pages — higher conversion, fewer size-related returns, and a lighter support inbox. These are their numbers, not ours.
How Merchants Use MP Size Chart
Each story covers the same three things: the sizing problem the store had, what they set up in the app, and what the numbers looked like afterwards.
Fashion & apparel
How Face 3 Face migrated 6,000 size charts and cut sizing questions to almost zero
A worldwide fashion store moved a 6,000-chart library off its previous app at no extra cost, then let automatic cm/inch conversion answer the question its support team kept fielding.
Personalized gifts & apparel
How Loveable lifted conversion 28.5% and cut apparel returns 18%
A U.S. personalized-gift store rolled out per-product charts, a size recommender, and automatic unit conversion across its apparel range — then measured the difference over three months.
What Changes When Sizing Stops Being a Guess
Different catalogs, different markets — but the stores in these case studies report the same three shifts.
Shoppers stop hesitating
A clear chart and a size recommendation on the product page remove the last unanswered question before add-to-cart.
Fewer wrong-size orders come back
Size-related returns are the most preventable kind. Accurate measurements shown at the right moment cut them down.
Support stops answering the same question
"Does this run true to size?" is the ticket that disappears first once the chart answers it on the page.
