You can choose where the size chart popup appears on your desktop storefront — centered over the page, or sliding in from the left or right edge as a full-height panel.
In the SmartSize app, go to Settings, open Size chart settings, and select Position. The live preview updates in real time as you try each option. Click Save to apply the change across your store.
Centered
Centered opens the size chart in the middle of the screen over a dimmed background. It puts the chart front and center — a good fit for most stores.

Right
Right slides the size chart in from the right edge as a full-height panel — the same behavior as Left, mirrored to the other side.
And on the storefront, the panel slides in from the right:
Good to know
The position applies to desktop storefronts. On mobile, the popup follows your Mobile layout setting instead.
Corner rounding only applies to the centered layout — the left and right panels always use square corners.
