3/8" white in practice
Opaque stock blocks light entirely, so at 3/8" the decision is structural and visual rather than optical — you are choosing how solid the piece needs to feel and look.
Solid enough to machine, tap and edge-finish like a workpiece rather than a sheet — the range where acrylic is being used as a component, not a covering.
In a laser: pigment absorbs the beam, so this cuts on a CO2 machine and on a diode, but 3/8" is beyond what a desktop diode will get through — treat it as CO2 stock.
3/8" white (color 7328) starts at $12.05 for a 12″ × 12″ piece at this thickness, and weighs about 2.34 lb per square foot, so a 24″ × 48″ piece comes to roughly 18.7 lb — worth knowing before you size a panel someone has to lift or ship.
Why 3/8" white acrylic?
A heavier, more substantial panel. 3/8″ resists flexing across wider spans, making it well suited to sturdier shelving, display bases, and panels that carry some weight or need to feel solid to the touch.
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.
