The weight of your sign depends on the material and size. Here’s a guide to help you estimate:

  1. HDU (High-Density Urethane): Signs
HDU weighs about 30 pounds per cubic foot. For example, a 1-inch thick HDU sign that’s 12″ x 12″ (1 square foot) would weigh approximately 2.5 pounds. As the size or thickness of the sign increases, the weight will adjust accordingly.
  2. Bronze Plaques:
The weight of a bronze plaque can be estimated by calculating the plaque’s volume (height x width x depth) in cubic inches, then multiplying by 0.31.
For smaller plaques (under 36″ x 30″), use a depth of 0.25″. For larger plaques (over 36″ x 30″), use a depth of 0.375″.
Example: A 36″ x 24″ bronze plaque would be calculated like this:
36″ x 24″ x 0.25″ = 216 cubic inches.
216 cu. in. x 0.31 = 66.96 lbs.
So, the estimated weight would be about 67 pounds.
  3. Aluminum Plaques:
Aluminum plaques weigh approximately one-third of the weight of a similarly sized bronze plaque. For example, if a bronze plaque weighs 67 pounds, a comparable aluminum plaque would weigh around 22 pounds.
