Logo too small. Minimum {LOGO_MIN_SIZE}x{LOGO_MIN_SIZE}. Got

Error message

Logo too small. Minimum {LOGO_MIN_SIZE}x{LOGO_MIN_SIZE}. Got {width}x{height}

What it means

Returned (400) when the square image is smaller than LOGO_MIN_SIZE (512px). Small sources would look blurry at display sizes, so the API enforces a minimum resolution.

Solutions

Export the logo at 512x512 or larger (1024x1024 recommended)
Get the original high-resolution asset from the design source instead of a downscaled copy
Only as a last resort, upscale with a quality scaler — prefer a true high-res source

Example fix

# design tool export settings
# before: 256x256 PNG
# after: 1024x1024 PNG (export scale 4x or original artboard)

Defensive patterns

Strategy: validation

Validate before calling

MIN = 512
if min(Image.open(path).size) < MIN:
    raise ValueError("export at 512px or larger")

Type guard

def meets_min_size(path: str, minimum: int = 512) -> bool:
    return min(Image.open(path).size) >= minimum

Try / catch

if resp.status_code == 400 and "too small" in resp.text:
        fetch_high_res_source_and_retry()

Prevention

Always export from the original design source, not thumbnails
Set export presets to 1024x1024
Reject tiny assets in the frontend picker

When it happens

Trigger: Uploading a 256x256 or 128x128 icon (typical favicon-sized assets).

Common situations: Using favicon.ico-adjacent exports; grabbing a small avatar/thumbnail version of the logo instead of the original; legacy brand assets created at low resolution.
