Doors & shelves
A cupboard has two jobs: hold your things and leave you room to move. Start with the space, then look at the doors and shelves.
Measure the awkward bits
Write down the width, depth and height. Include skirting boards, sockets and the space a door needs to swing.
Check the inside
Outside dimensions tell you whether the cupboard fits. Shelf dimensions tell you whether your things fit.
Plan assembly
Check the delivery route, assembly instructions and any wall-fixing requirements for the model you choose.
