There are five main sizes of doorplates. One is the doorplate, 400 mm× 600 mm, which is generally suitable for the gates of courtyards or high-rise buildings, mostly used by units, and the background color of doorplates is mostly blue.

If it's just the store manager's office, the length can be 30-40 cm, and the width can be about 12- 18 cm. You can adjust yourself according to your feelings. You can make a piece of paper about the same size, put it by the door to see if it fits, and then click it. The same is true of listing. The best way is to make a piece of paper and see how it feels with the scene, and finally decide the size.
