One structured pass over every size, before anything is exported.
The review gate is where a campaign either ships cleanly or generates a second round. Working through the same checks in the same order on each output keeps that gate short and predictable.
- Ten check areas
- Reviewed at real ratio
- Editable until export
- No credit card required · Full per-size control
Eight things to look at on each output.
Work through them in this order. Layout issues are cheaper to fix before typography, and typography before final export settings.
Safe areas
Nothing essential sits in the bands covered by platform interface elements, particularly at the top and bottom of vertical placements.
Text clipping and wrapping
No clipped descenders or diacritics, no orphaned single words, and no headline that gained an extra line in this ratio.
CTA visibility
The call to action is fully visible, clear of UI overlays and edge margins, and consistent in style with the rest of the set.
Image framing
The subject is framed deliberately, never cropped at the face or through a product, and the background is extended rather than stretched.
Logo clearance
Logo size, clear space and position follow the brand rules, and remain legible in the smallest unit in the set.
Font rendering
Correct family and weight throughout, no synthesised bold or italic, and no substituted face in localized versions.
RTL and LTR direction
Alignment, reading order and mirrored elements follow the language of the copy, not the direction of the original master.
Contrast
Text remains legible against whatever part of the image sits behind it in this particular ratio.
Platform-specific requirements.
Requirements differ by platform and change over time. Confirm the current guidance for each placement in the media plan rather than reusing last year's list.
- Ratio and pixel dimensions match the placement being bought
- File format and file size are within the platform's limits
- Text density suits the placement and reads on a small screen
- Vertical placements respect the platform's UI bands
- Any required disclaimer or legal line is present and legible
- Localized versions exist for every market in the plan
Export verification.
- Every required size is present in the exported set
- Dimensions and file format correct for each placement
- File naming consistent and readable for the media team
- Each file opens and renders as approved on screen
- One export spot-checked against the on-screen preview
- Delivery package matches the placement list in the brief
The review gate in context.
This checklist is the last stage of the Tadvio production workflow. The issues it catches are described in why approved creatives break in new formats, the size and placement definitions live in the ad format reference, and the typography checks are expanded in custom fonts across multi-market production. For how the review gate sits inside a wider operating model, see creative operations.
