How the calculation works
V14 calculation: recommendedLengthMin=sofaLength×0.40; recommendedLengthMax=sofaLength×0.67; maxDepth=max(0,availableGap-walkway); recommendedHeightMin=max(0,seatHeight-0.05); recommendedHeightMax=seatHeight+0.05. This is the implementation specification for this calculator.
Worked example
Example: Sofa length = 210 cm; Sofa seat height = 45 cm; Available sofa-to-TV gap = 110 cm; Required remaining walkway = 50 cm. Result: Recommended Height Max = 50 cm; Recommended Height Min = 40 cm; Max Depth = 60 cm; Recommended Length Max = 140.7 cm.
