Round the corners of the fit quiz popup so it matches the look of your theme, or set them back to fully square. It is one store-wide setting, and this article shows both directions.
Add rounded corners
In your Shopify admin, open SmartSize → Settings. In the Sections menu on the left, scroll to Fit quiz settings and click Corner rounding. Drag the slider or enter an exact number in Corner radius (px) — any value from 0 to 35 px works, and the default is 12 px. The preview on the right shows the rounding as you adjust it.

Click Save. On your storefront, the fit quiz popup now opens with rounded corners:

Remove rounded corners
Want square corners instead? Set Corner radius (px) to 0 — drag the slider all the way to the left or type the number directly into the field — and click Save.

The popup now opens with completely square corners:

💡 Tip: A quick way to pick a value is to match the rounding of your theme's buttons and cards. Subtle values between 8 and 16 px look natural on most stores.
