Planning notes for Siding Linear Feet Calculator

500 sq ft of siding with a 6 in exposure needs 1,000 LF before waste.

Good for

  • wood siding
  • cladding boards
  • rainscreen material planning

How to use it

  • Enter wall area after subtracting large openings.
  • Use exposed face width.
  • Add waste for corners and cutoffs.
Formula check: Siding LF equals wall area divided by exposed board width in feet.

Quick Conversions

100 sq ft at 6 in width

200 LF

6 in

LF = (100 x 12) / 6

200 sq ft at 5.5 in width

436.4 LF

5.5 in

LF = (200 x 12) / 5.5

500 sq ft at 12 in roll width

500 LF

12 in roll

LF = (500 x 12) / 12

1000 sq ft at 16 in width

750 LF

16 in

LF = (1000 x 12) / 16

Use Cases

Flooring and Decking

LF = area / plank width

Example

240 sq ft at 6 in width

480 LF

Baseboard and Trim

LF = room perimeter - openings

Example

120 ft perimeter + 2 doors

168 LF

Fencing

Panels = fence line / panel width

Example

200 ft fence line

25 panels

Freight Pallets

LF = trailer length used

Example

53 ft trailer length

212 LF

Board Feet and Lumber

LF = board feet x 12 / size

Example

100 BF, 2 x 6

100 LF
