Magazine A wall sign's mounting location is determined by the available facade space as well as the customer's specifications.
Some customers have definite installation plans with all dimensions verified in advance.
Other customers may provide verbal instructions aobut the sign's mounting location without knowing the actual dimensions. Installers should always verify the precise mounting location before making a trip to the jobsite. You can't assume that the owner will be present when you arrive to install the signs, and nobody's going to pay you to wait. Normally, customers want wall signs centered vertically and horizontally on rectangular facades. This means that there will be equal margins at the top, bottom and each side of the sign.
