Our first pipe, typically from three quarter inch up to one and a quarter inch in diameter, you will wanna use a label size that's one inch wide by eight inches long. Make sure your font size is a half inch which is sufficient for clear visibility.

For large pipes greater than six inches and up to ten inches in diameter, opt for a label size of three inches wide by twenty four inches long.
