Twitch オフラインバナーのサイズ変更に関するよくある質問
Answers about 1920x1080 offline banner sizing, schedule text, social handles, background art, crop choices, and export formats.
This page prepares a 1920x1080 image for a Twitch offline banner. The full HD format gives you room for channel art, schedules, social handles, community messages, sponsor notes, and visual branding when visitors land on your channel while you are offline.
An offline banner usually works best with a clear channel name, stream schedule, social handles, and a short message about when viewers can return. You can also include character art, background scenes, or branding that matches the rest of your Twitch identity.
A schedule is helpful if you stream regularly. Keep it short and easy to read, with timezone information if needed. Avoid long paragraphs because visitors may only glance at the offline screen before deciding whether to follow or check another link.
You can reuse colors, logos, and art direction, but overlays often contain frames and widgets that do not make sense offline. A dedicated banner should feel calmer, with enough open space for schedule text and a clear channel message.
JPG works well for full-screen artwork, photos, gradients, and illustrated backgrounds. PNG is better for banners with text, logos, flat shapes, panels, and clean graphic edges. Choose the format that keeps the banner readable without unnecessary file weight.
Yes, but vertical artwork may need cropping, side background, or repositioning to fill the 1920x1080 frame. Use the preview to check that characters, faces, schedule text, and logos are not cut off or pushed too close to the edge.
Use a clear hierarchy: channel name, schedule, socials, and background art. Leave breathing room between sections and avoid placing text over the busiest part of the image. A clean offline banner should be easy to scan in a few seconds.
Check whether the schedule is readable, whether the branding matches your channel, and whether important artwork is cropped correctly. If the banner feels too busy or the text blends into the background, adjust the crop or contrast before saving.
