    Twitter Header Size

    X's help page recommends 1500 × 500 pixels (3:1) for a header photo, as a JPG, GIF or PNG; animated GIFs are not supported.

    Specs checked: 6 October 2026

    The header, also called the banner, runs across the top of your X profile. X's help page gives 1500 × 500 as the recommended size and lists JPG, GIF and PNG, but it does not give a file size limit.

    Your profile photo, 400 × 400, sits over part of the header, and the header is shown at different widths on phones and computers. Test your image below, then resize it to 1500 × 500.

    Header and profile photo

    Diagram: Header and profile photoHeader 1500 × 500 (3:1)Profile photo (rough marker)

    The frame is 1500 × 500, a 3:1 ratio. The circle is a rough marker for the profile photo, which overlaps the header; X does not publish its exact position or size on the header.

    The edges of the header can be cut off on some screens, so keep text near the middle and check your profile on a phone and a computer after uploading.

    Planning around the profile photo

    The profile photo covers part of the header on your profile page, so that part of the header image is never fully visible. Keep text and faces away from where it sits and check the preview after uploading.

    Because the overlap depends on the device, a simple background with a short line of text near the centre is easier to keep readable than a busy design.

    Still images only

    X lists GIF as an accepted format but says animated GIFs are not supported for header photos. Export a still frame instead.

    X's help page gives no file size limit for headers. A 1500 × 500 JPG is usually small, so file size rarely matters here.

    Tips

    • Design at 1500 × 500 and keep the main message in the middle of the frame.
    • Use PNG for headers made of flat colours or text, and JPG for photos.
    • Match the header's colours to your profile photo so the overlap looks deliberate.
    • Check your profile on a phone after changing the header, since the width differs from a computer.

    Common mistakes

    • Uploading an animated GIF and expecting it to move.
    • Using a 16:9 photo, which is much taller than 3:1 and loses much of its height.
    • Putting a handle or slogan where the profile photo covers it.
    • Placing text against the left or right edge, which can be trimmed on some screens.

    Frequently asked questions

    What size is a Twitter header?

    X's help page recommends 1500 × 500 pixels, a 3:1 ratio. The same image is called a header or a banner.

    Is there a file size limit for X headers?

    X's help page does not state one for header photos. Keeping the file small still helps it load quickly.

    Can my X header be a GIF?

    You can upload a GIF, but X does not support animated GIFs for headers, so use a still image.

    What size is an X profile photo?

    X recommends 400 × 400 pixels, as a JPG, GIF or PNG. Animated GIFs are not supported there either.

    Why is my X header cropped?

    The header is shown at different widths on different screens, so the edges can be trimmed, and the profile photo covers part of it. Keep important content near the centre.
