Make a 2560 x 1440 banner and see the centre strip that shows on every device.
Check whether a size is 16:9, 16:10 or 4:3 before you design.
An aspect ratio is width divided by height, written in the smallest whole numbers. Divide both sides by their greatest common divisor: 1920 and 1080 share 120, so 1920 x 1080 is 16:9. 1080 x 1350 shares 270, so it is 4:5.
Some sizes do not reduce to small numbers. 1546 x 423 has no common divisor, so its exact ratio is 1546:423. The tool also shows it as a decimal (3.65:1) and as the nearest simple ratio (about 11:3).
It is the YouTube channel banner safe area at the recommended 2560 x 1440 size. YouTube Help gives the safe area as 1235 x 338 px at the 2048 x 1152 minimum; scaled up to 2560 x 1440 that is about 1544 x 423, usually quoted as 1546 x 423. Only that centre strip shows on every device, so keep text and logos inside it. Pick the YouTube channel banner preset to see it on your image.
