Frequently Asked Questions
Got questions? Find clear answers below.
What size is a Twitter banner?
The standard Twitter banner size is 1500 pixels wide by 500 pixels tall, which corresponds to an exact 3:1 aspect ratio. Designing or resizing your banner to 1500x500 px delivers crystal-clear rendering across widescreen desktop displays, retina laptops, tablets, and mobile devices without pixelation or unwanted distortion.
What size is an X header?
An X header has the exact same dimensions as a Twitter banner: 1500 x 500 pixels (3:1 aspect ratio). When Twitter rebranded to X, the profile dimension guidelines and banner specifications remained identical. The recommended file size is under 2MB (with a maximum upload limit of 5MB) in JPG, PNG, or WebP format.
Why is my banner cropped?
Twitter crops header images differently depending on the user's screen resolution, device aspect ratio, and browser viewport. On smartphones, the official X app trims approximately 60 pixels from the top and bottom edges (or slightly crops the sides). Additionally, your circular profile avatar permanently overlaps the lower-left section of the banner on all devices, covering any text or graphics placed in that corner.
What is the safe zone?
The Twitter banner safe zone is the central horizontal region (approximately 1200 x 380 pixels) that avoids the bottom-left avatar overlap and leaves at least 60 pixels of breathing room from the top and bottom borders. Placing all critical graphics, company logos, contact information, and slogans inside this safe zone ensures they remain 100% visible on every device without being cropped or covered.
Should I use PNG or JPG?
Use PNG if your Twitter banner contains logos, sharp typography, vector graphics, or high-contrast illustrations because PNG preserves crisp edges without lossy compression artifacts. Use JPG if your banner is a photograph, scenic background, or complex image with many colors, as JPG produces a smaller file size that loads much faster over mobile networks while keeping visual clarity high.
