Measure one room consistently at finished surfaces and note which walls, floors and edges actually receive new material.
The combined estimate derives wall area, floor requirement, paint and skirting from the same dimensions so early options remain comparable.
Use the result to establish a first budget, then open the dedicated calculator for each chosen material and enter its real pack or coverage data.
A single room figure cannot include substrate repair, services, demolition, doors, trim and specialist labour unless they are priced separately.
Use the units beside each field. The values in the worked example are starting inputs; replace them with your measurements and the specifications of your material.
