1/4" white in practice
Opaque stock blocks light entirely, so at 1/4" the decision is structural and visual rather than optical — you are choosing how solid the piece needs to feel and look.
This is the first thickness that stands up on its own: rigid enough for free-standing pieces, risers and structural parts rather than only framed panels.
In a laser: pigment absorbs the beam, so this cuts on a CO2 machine and on a diode, though a diode will need several passes at this thickness.
1/4" white (color 7328) starts at $6.79 for a 12″ × 12″ piece at this thickness, and weighs about 1.56 lb per square foot, so a 24″ × 48″ piece comes to roughly 12.5 lb — worth knowing before you size a panel someone has to lift or ship.
Why 1/4" white acrylic?
The all-purpose workhorse and our most popular thickness. At 1/4″, acrylic is rigid enough to stand on its own in most sizes, which is why it's the default for tabletops, shelving, risers, desk shields, and protective barriers. If you're unsure which thickness to choose, this is usually the right starting point.
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.
