How to specify acrylic thickness and letter depth
Acrylic sheet thickness and the overall depth of a built-up letter are different dimensions. A brief should identify which dimension is being discussed, the role of the acrylic and whether the sign is illuminated. There is no single thickness that suits every artwork and mounting condition.
Identify what the acrylic does
A clear panel, a solid cut letter and a light-diffusing face place different demands on the material. Mark the visible face, edges, supports and lit areas on a drawing. Share the artwork at the intended size so fine strokes, counters and fixing positions can be considered. A material description without the actual geometry cannot resolve those decisions.
Compare the front and side views
A sign may look convincing in a flat visual while appearing different from the corridor or pavement. Ask the drawings or sample to show the letter depth, exposed edges, stand-offs and background. Discuss whether visible fasteners suit the intended appearance. Record the overall projection from the wall so adjacent finishes, furniture or doors can be considered before fabrication.
Review illuminated components as an assembly
For illuminated signage, the face, light source, internal space and construction need to be selected together. Review a representative part of the artwork rather than a generic square sample. Manufacturer material guidance can help identify appropriate optical properties, but it does not replace a sample of the proposed sign. Agree the daytime and illuminated appearance before the full set is approved.
Document mounting and care
Provide the wall substrate and access restrictions with the brief. The fixing design must suit the sign and its support, rather than being chosen from thickness alone. Ask for cleaning instructions compatible with the acrylic and any applied finish. Keep the material reference, sample and final dimensions with the drawing record for future repair or matching additions.
