Technical Specifications for Web Banners
A short, exact guide to preparing banner assets that display flawlessly across every USA ONBOARD site, and pass review the first time.
Three formats, three exact sizes.
Supply each creative at these exact pixel dimensions. Assets that do not match will not pass review.
How each file should be built.
Four things keep your banner sharp and fast on every screen.
File Formats
Static or animated, in any of these formats.
Maximum File Size
150 KB per banner, optimized for fast web loading. Lighter files load and render better.
Color Profile
RGB or sRGB. CMYK and print files are not supported and will display the wrong colors.
Resolution
Web standard, screen-optimized. What matters is the exact pixel size above; DPI does not affect on-screen display.
What every banner needs to go live.
A destination link is required
Every banner size you upload must include a valid destination URL. No banner goes live without one.
Multiple variants rotate evenly
Upload more than one banner for the same size and they will be rotated evenly, with equal exposure for each variant.
Review needs image plus link
Each banner requires both an image asset and a destination URL before the campaign can be submitted for review.
Keep animation short and light.
For animated GIFs we recommend a maximum duration of 15 seconds and a loop limit of 3. It delivers the best user experience and keeps you aligned with modern browser standards.
