Toilet sign size

Quick answer：

The size of toilet signs typically varies by country and specific building codes. Generally, they should be large enough to be easily read from a distance, often between 6 to 12 inches in height. In public spaces, signs should comply with ADA (Americans with Disabilities Act) guidelines, which specify that signs must be at least 5.5 inches high with a 3-inch stroke width. For international contexts, signage should adhere to the ISO 7001 standard for graphical symbols.
