Canvas
Set the size of the design surface, the area guests can actually edit, and optional masks or rounded shapes.
Canvas size
Set the overall canvas width and height in pixels. Turn on **Front/Back Canvas** to design two sides — each side gets its own dimensions, editable area, and background.
Editable area
The editable area is the region inside the canvas guests can actually place content in — everything outside it is background.
Position & size
Set X/Y offset and width/height in pixels; the area can't exceed the canvas bounds.
Rounded area
Turn the editable area into a circle or oval instead of a rectangle.
Custom mask
Upload a PNG or SVG mask to shape the editable area into anything — a mug, a card cutout, a logo silhouette.
Background color & image
Set a solid fill color or background image shown behind the editable area.
Masks vs. rounded areas
Rounded Area and Custom Mask are mutually exclusive — turning one on turns the other off. Use Rounded Area for a simple circle or oval, and a Custom Mask for any other shape.
Back canvas
When Front/Back Canvas is enabled, the Back Canvas section mirrors the front exactly — its own dimensions, editable area, rounded/mask option, and background — so guests can design both sides of a product like a card or a mug.
Use the live Canvas Preview to drag the editable area directly instead of typing coordinates — it updates the X/Y/width/height fields for you.
