Laser-cut in the Curbmark address font, which is built to be read from the street. Pick a size, acrylic or wood, and colors, then order on Etsy with your design code.
Many towns require house numbers at least 4" tall with a stroke at least ½" wide, readable from the street. Check your local rules. A Large plaque with just the number gets you to about 4" or more. The preview shows your exact height.
Your numbers are cut through a top layer, with a contrasting backer showing through. Curbmark Plate keeps the centers of 0, 6, 8 and 9 attached, so nothing goes missing.
USPS has long asked for numbers at least 1" tall in a contrasting color on the side of the box. The Small plaque fits most mailbox posts.
Curbmark is also sold as a font with cut files, for makers who do their own lettering. See the font on Etsy.
