What is the Google Forms Header Image Size?
Google Forms uses a wide banner image at the top of every form. The recommended and ideal Google Forms header image size is 1600×400 pixels — a 4:1 aspect ratio. This dimension ensures your header looks sharp on all screens, from desktop monitors to mobile phones.
If you upload an image with different proportions, Google Forms will crop it automatically — often cutting off important content. Using this free cropper lets you control exactly what appears in the header before you upload it to your form.
Images that are too small may appear blurry or pixelated when displayed as a Google Forms header. For best results, always start with a source image that is at least 1600 pixels wide.
Supported Image Formats for Google Forms Headers
- JPG / JPEG — Best for photos and complex images; smaller file size
- PNG — Best for logos, illustrations, and images with transparency
- WebP — Modern format with excellent quality-to-size ratio
- GIF — Supported, but only the first frame will be used (no animation)
Tips for a Perfect Google Forms Header
If you plan to overlay text on the banner, ensure strong contrast between the background and any text to keep it readable.
Google Forms may slightly trim the edges on some screen sizes. Position your logo or focal point in the center of the banner.
Text smaller than 24px is nearly unreadable in a 1600×400 header when displayed on mobile. Use large, bold typography only.
Match the header image to your theme color in Google Forms Settings → Customize theme for a professional, cohesive look.
Use PNG if your header has a logo with a transparent background. For full-bleed photographs, JPG produces a smaller file at high quality.
Always preview your Google Form on a smartphone before sharing. Mobile devices crop the banner more aggressively than desktop.
