Every banner checked before you see it.

Sizewright measures each banner on its rendered pixels against thirteen rules, has a vision model review it the way an art director would, and fixes what they find. A banner that still fails is marked for your attention, never exported and never charged.

Example. The 300 × 600 for Maison Lumière, a fictional brand, passed every check listed here without a fix or a warning.

Three layers

  • Measured rules

    Contrast against the actual pixels behind each line, the smallest type size, overflow, safe zones, logo size and clear space, copy kept off the photo’s subject, the button’s prominence, your palette, image sharpness, animation limits, the copy itself, compared letter by letter, and every line your brief requires.

  • A designer’s eye

    A vision model scores the finished banner on hierarchy, legibility, brand fidelity, composition, imagery, message clarity and polish. A banner passes with no score below three out of five and an average of at least four.

  • Fixed, then checked again

    Automatic fixes strengthen a scrim, switch text to the better contrasting brand color or outline the button. The review’s notes shorten copy, try the next layout variant or re-crop the image. Then every check runs again.

Thirteen rules, on every banner.

They run on every banner of every build, and again each time you save an edit, at no cost.

Questions, answered.

What happens to a banner that fails?

It stays in your set, marked as needing attention, with the reason. It is left out of exports and client approval links, and its credits are not charged. Fix it in the editor and the checks run again.

Do the checks run again after I edit?

Yes. Every save runs the thirteen measured rules again, for free, and the editor shows them live while you work. A new review by the vision model runs when you ask for one.

Does the vision model review every banner?

Every banner of a new build, unless the job reaches its cost limit first; then the rest are delivered on the measured rules and you can ask for the review later. Edited banners and bulk variants get the measured rules on every save, and the review on request.
