Your logo replaces your name in the website header, so it should clearly include your brand or name. Wide logos work best (recommended aspect ratio: 4:1-15:1). For the Small logo size, recommended dimensions are about 800px x 200px; for the Large size, about 1600px x 400px. If your logo is smaller, increasing the logo size in settings may have little visible effect.
Maximum file size is 150KB. Supported formats: PNG, JPG, and GIF. Transparent backgrounds are recommended. Depending on your logo's shape, size, and layout adjustments may be less noticeable on mobile screens.
