A4 storage box — frequently asked questions

What size is the WestonBoxes A4 storage box and what does it hold?

The A4 storage box measures 312 x 225 x 57mm externally and 304 x 216 x 55mm internally. It holds a full ream of 500 sheets of 80gsm A4 paper. The internal dimensions are sized to hold A4 paper flat without movement, with enough clearance to prevent corner-curl.

What else can I store in an A4 box besides paper?

The A4 box is one of the most versatile sizes in the range. Customers use it for card stock, watercolour paper, art prints, certificates, presentation documents, craft supplies, ink pads, stamps, washi tape collections, fabric scraps, and general stationery. If it fits within 304 x 216mm and is no taller than 55mm, it will store neatly in an A4 box.
