A yard sign is the cheapest square footage of advertising you can buy — but only if it stays up, stays flat and can actually be read from a moving car. Those three outcomes are decided by choices most people click through without thinking. Here is what each one does.
Coroplast thickness: stiffness, not waterproofing
All corrugated plastic is equally waterproof. What thickness buys is stiffness. Our yard signs print on 4mm coroplast, the standard for elections, open houses, event directionals and weekend campaigns — light, cheap and easy to stake, and light enough to carry a dozen at a time. Heavier 6mm, 8mm and 10mm grades trade that portability for rigidity: they hold their plane through a full season outdoors and stay straight across large exposed panels that would otherwise start to bow.
Grommets or stakes — pick your mounting first
Grommets are reinforced metal rings for hanging or zip-tying a sign. If your sign goes on an H-stake in the ground, choose no grommets — the stake's legs slide up inside the hollow flutes of the coroplast, no holes needed. Choose corner grommets for fence mounting, real-estate patterns for hanging frames, and every-2-3-feet patterns for large panels where wind load needs spreading across many fixings.
One stake or two?
One H-stake per sign up to 18" x 24" in normal soil. Two stakes for anything 24" wide or wider — a single stake in a wide sign lets it pivot in wind until the flutes tear. Push stakes in by the horizontal bar, never by pressing on the sign, and get the legs at least six inches down.
Sizing for reading distance
Allow roughly ten feet of readable distance for every inch of letter height. An 18" x 24" sign with a 3-inch headline reads from about 30 feet — fine for a residential street. For 40 mph traffic, go 24" x 36" or larger, cut the message to six words, and make the phone number the second biggest element. High contrast beats clever design at every speed.
Single or double sided?
Print one side for signs against a wall or fence. Print two sides with the same image for signs staked where traffic passes both directions. Print two different images when each direction needs its own message — such as opposite-pointing arrows.
On hard surfaces where stakes cannot go in, plan on a fence fixing or a wall mount instead and order the matching grommet pattern. And as with everything we print, artwork gets a free hand check before production.
