How the calculation works
V14 calculation: recommendedWidthMin=sofaSeatWidth×0.50; recommendedWidthMax=sofaSeatWidth×0.80; maxDepth=max(0,availableFloorDepth-clearGap); recommendedHeight=seatHeight. This is the implementation specification for this calculator.
Worked example
Example: Sofa seat width = 175 cm; Desired gap from seating = 5 cm; Available floor depth = 60 cm; Sofa seat height = 45 cm. Result: Recommended Height = 45 cm; Max Depth = 55 cm; Recommended Width Max = 140 cm; Recommended Width Min = 87.5 cm.
