This tool returns the exact pixel dimensions and export settings for every Twitch channel image — profile picture, profile banner, and the offline video screen. Each asset has its own recommended size, aspect ratio and crop behaviour, and getting them right keeps your channel looking sharp instead of stretched or pixelated.
How it works
Pick an asset and the tool reads its spec from a built-in table of Twitch’s recommended dimensions: the upload size, aspect ratio, accepted formats and file-size cap. Profile pictures are square but masked into a circle, the profile banner is a wide 2.5:1 strip across the top of your channel, and the offline video banner fills the 16:9 player frame.
The tip line for each asset reminds you how Twitch crops or masks it, so you can keep key content — your face, logo or text — inside the area that actually stays visible.
Tips
- Centre your logo or face in the profile picture; the circular mask hides the corners of a square upload.
- Design the profile banner so important text sits in the middle — the strip is wide and short, and edges can be trimmed on narrow viewports.
- Use the offline banner to advertise your schedule or socials; it is the first thing visitors see when you are not live.
