1/8" white in practice
Opaque stock blocks light entirely, so at 1/8" the decision is structural and visual rather than optical — you are choosing how solid the piece needs to feel and look.
This is the lightest thickness that still holds itself flat in a frame, which is why it is the default for signage faces and glazing where something else carries the load.
In a laser: pigment absorbs the beam, so this cuts on a CO2 machine and on a diode, and at this thickness a diode will usually manage it in a pass or two.
1/8" white (color 3015) starts at $4.48 for a 12″ × 12″ piece at this thickness, and weighs about 0.78 lb per square foot, so a 24″ × 48″ piece comes to roughly 6.2 lb — worth knowing before you size a panel someone has to lift or ship.
Why 1/8" white acrylic?
The thinnest acrylic most jobs call for, and the most economical. At 1/8″ it stays light and easy to handle, which makes it a go-to for signage, glazing, picture-frame glass, and point-of-purchase displays. It has some flex in larger panels, so it's best where it's framed or supported rather than free-standing.
About White acrylic
White 3015 is our workhorse opaque white — a bright, solid, glossy sheet that blocks light completely. It's the standard for sign faces, retail fixtures, and panel work: anywhere you want a clean finished white surface rather than a glow. Because it's opaque, back-lighting won't pass through — choose a translucent white for light boxes.
