Sales units
These rows come from the same sales-unit policy used at quote and checkout. They are not a second price list, and not every record in a category uses the same unit if the policy has an exception.
Most lumber, siding, paneling, trim, and decking wood
Sales unit: LF
Square footage and piece counts plan coverage. They are not the sell quantity.
Tropical decking planned on the Ipe owner page is sold by linear foot. Exact lengths set the board count.
Flooring
Sales unit: SF OR LF
Verified flooring products may be quoted in square feet or linear feet. The available units and conversion come from the selected product.
Catalog default stays square feet. Linear feet are available only when a verified face conversion exists. Bark remains square-foot based.
Bark siding
Sales unit: SF
Coverage is planned and sold in square feet for approved bark products.
Do not convert bark coverage into lumber linear feet.
Roofing
Sales unit: SF OR SQ
Approved roofing is sold by square foot or by square, matching the product record.
Ambiguous square-unit items are not converted automatically. We confirm the unit before quoting.
Hardware and accessories
Sales unit: EA
Clips, screws, bits, and similar items stay each or package.
Hardware is never folded into lumber linear feet or deck square footage.
Items that need confirmation
Sales unit: CONFIRM
Keep the catalog unit until Timberline confirms it.
These lines are not silently converted to LF, SF, or SQ.
What is a lineal foot?
A lineal foot (LF) is one foot of board length, regardless of width or thickness. When wood is sold in LF, the sell quantity is length, not project square footage.
Board feet (BF) remain a volume measure: (Thickness in × Width in × Length ft) ÷ 12. We may still show BF for explanation; it is not the default sales unit for finish lumber and decking.
Square feet as planning
If you know project area, you can convert to lineal feet with an example face width:
Face widths in the sidebar calculator are examples only. Locked faces and special cart contracts live on the species planners:
- Ipe project planner
- Eastern White Pine, Cedar, Cypress
- Arkansas Yellow Pine, Douglas Fir, Poplar bark siding
Waste is a selected planning allowance, not a required percentage for every job.
Pricing FAQ
Approved flooring lines are sold in square feet, not lineal feet. Use the Arkansas Yellow Pine planner for locked flooring faces, or request a quote for other species.
Random Lengths (RL) means an assortment of board lengths rather than one uniform length. Some products are also sold in exact lengths when those records are priced. Confirm the mix on the current product or planner.
Some catalog items (for example ambiguous square units) cannot be converted automatically. Those lines stay on the catalog unit until Timberline confirms them. They are not silently rewritten to LF or SF.
