Why 1080×1920 Is a Common Target Size

Preset dimensions save rejection loops

Portals, ad managers, and CMS fields often hard-cap uploads at 1080×1920. Resizing before upload prevents automatic cropping, blurry upscaling, or silent compression that wrecks your creative.

Portrait geometry at a glance

Tall canvases fit Stories, mobile feeds, and vertical video covers where vertical scroll is the default gaze.

Pixel-exact export locally

Canvas draws to your exact width and height integers — no cloud rounding. Files never leave your device, so NDAs and personal photos stay private.
