Picture Hanging Calculator — Hook Position & Wire Length
Calculate hook positions, wire length, and wall anchor type based on frame weight and dimensions.
How We Calculate This
How Picture Hanging Calculation Works
Hook height = Frame top position - Wire drop
The calculator places the frame centre at eye level (default 1500 mm), then calculates the hook position accounting for wire sag or D-ring offset. Wire length is computed using the D-ring spacing, drop distance and extra length for tying knots.
