Matboard is typically measured in PLY, which is not standardized like inches, making it misleading. Mats come in either
4 PLY (0.040-0.052″)
or 8 PLY (0.125″) but that doesn’t mean all PLY are the same. For example, there are 0.040″ 4 PLY and 0.052″ 4 PLY.
Double or triple 4 PLY mats can also be used in place of 8 PLY mats to get a similar effect.
The thicker the photo mat is, typically the higher the quality and price are. The advantages of a thicker matboard are:
- Depth: greater depth in the art work gives a much more professional look
- Sturdiness: a very thin matboard will bend or warp, especially on larger matboards
Berkshire mats are 0.040″ thick as compared to 0.052″ for the Decorative and Conservation mats, which is part of why Berkshire is the cheapest mat. Conservation matting also comes in 8 PLY and they are our highest quality matboard.
