36 main and promo banners
A set of banners where each campaign is reworked for three sizes: desktop main, mobile main and promo strip.

1Problem
If you just shrink a desktop banner for mobile, the text gets tiny and the button ends up far from the thumb.
Narrower screens cut off the sides, and if the price or button sits there, the banner stops doing its job.
2Process
- 01On desktop banners, the key copy, price and button stay inside the center 1200px.
- 02Mobile banners are not shrunk desktop banners. They are restacked top to bottom, with the price and button down low where the thumb reaches.
- 03Promo strips use numbers and short lists so the offer and dates read at a glance in a 400px height.
3Result
- 3612 desktop main, 12 mobile main, 12 strips
- 3 sizes1920×700, 750×1000, 1200×400
