Logo must be square. Got {width}x{height}

Error message

Logo must be square. Got {width}x{height}

What it means

Returned (400) after Pillow reports the image's dimensions and width != height. Logos must be exactly square; any aspect ratio other than 1:1 is rejected before the min/max size checks.

Solutions

1. Crop or pad the image to a square canvas (e.g. 1024x1024) before uploading
2. Center the mark on a transparent square background for non-square logos
3. Automate squaring in your asset pipeline

Example fix

# python
from PIL import Image
img = Image.open("logo.png")
# after: pad to square
side = max(img.size)
sq = Image.new("RGBA", (side, side), (0, 0, 0, 0))
sq.paste(img, ((side - img.width) // 2, (side - img.height) // 2))
sq.save("logo-square.png")

from PIL import Image
w, h = Image.open(path).size
if w != h:
    raise ValueError(f"pad/crop to square first, got {w}x{h}")

def is_square(path: str) -> bool:
    w, h = Image.open(path).size
    return w == h

if resp.status_code == 400 and "must be square" in resp.text:
        pad_to_square_and_retry()

When it happens

Trigger: Uploading a 1024x768 rectangle, a rounded logo on a non-square canvas, or an image with uneven padding.

Common situations: Marketing assets produced in 16:9 or 4:3; screenshots cropped loosely around a mark; batch exports that preserve source aspect ratio.
