Frequently Asked Questions
Find answers to common questions about this product
Not sure what thickness you need? Read the Greyboard Guide
1000 micron (1 mm) greyboard is slightly lighter and easier to cut, making it ideal for school projects, lightweight backing, or craft applications. 1500 micron (1.5 mm) greyboard is heavier and stiffer, best for model making, mounting artwork, or when extra durability is required. - Not sure what weight ot

The right size depends on your project:
A5: Small projects, postcards, book covers
A4: School displays, craft sheets, signage backings
A3: Artwork mounting, model bases
A2: Large displays, structural craft, portfolios
SRA1: Oversized sheets (640 × 900 mm) for trimming down or large-scale work
