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 7328) starts at $4.00 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 we stock, 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 7328 is an opaque glossy white, its own shade among our whites. It blocks light completely and reads as a bright, reflective panel from any angle, lit or not. Use it for sign faces, fixtures, and finished panels where a glossy white surface is wanted; for a white that glows from behind, choose one of our translucent whites. For an exact match to existing material, ask us to confirm the lot.
Made to order. Not every color and thickness is stocked at all times — if yours is temporarily out, we make or source it and ship as soon as it's back in stock. On a deadline? Email us before you order and we'll confirm your expected ship date.
