Letter Heights may not measure true to the size. The font is set so that the tallest letter in the kit matches the size of the kit or the size of the letter. Pleas note that lower case letters are meant to be used along side the capital letters of the same size and therefor may not measure the height stated. Please contact us if you have any questions or if you would like to request a special font or special size not listed. 800-966-0975 or sales@magnetking.com
