Canvas dimensions set the frame size and aspect ratio for your entire project. You choose the dimensions at the start, and every component, template, and scene is laid out to fit that frame, so what you build is already sized for where you plan to use it.

Why It Matters
Templates and components adapt to the canvas size you select. A portrait canvas gives more vertical space for mobile app flows and tighter callouts, while a landscape canvas makes room for environments, labels, and side-by-side layouts. Picking the right dimensions up front means less rework when you export.
