Understanding Linear Feet vs. Square Feet

When ordering reclaimed wood, it’s easy to confuse linear feet with square feet. Linear feet measure only length, while square feet measure area (length × width). If you know the total length of boards you have, you’ll need to factor in their width to determine how much surface area they’ll cover. This is especially important in projects using boards of varying widths. For example, 100 linear feet of 6" boards will cover less area than 100 linear feet of 8" boards. Our calculator helps translate linear footage into square footage, so you can plan your project more accurately, avoid costly over-ordering, and prevent delays from running short.

Do I need this calculator to order wood from E&K Vintage Wood?

No, you do not need to use the linear feet calculator when requesting a quote and placing an order. We only need the total square footage to provide a quote. This calculator is for your convenience—to help you understand how much surface area your linear feet will cover.

What is this calculator used for?

The linear feet calculator is a tool for converting linear feet into square feet of coverage. Use it to verify your order, track usage during installation, or estimate coverage from leftover material.

How do I convert linear feet to square feet for siding?

The formula to convert linear feet to square feet for siding is to multiply the total linear feet by the board width of your siding boards (in feet). For example, 400 linear feet × 0.5 ft (6-inch board) = 200 square feet. Our Linear Feet Calculator above handles this automatically—just enter your linear footage and board width in inches.

What is 'board width' and why does it matter in this calculator?

This calculator uses the board width to determine how much surface area your linear footage will actually cover. If you’re requesting a quote and order from E&K, you only need to tell us the square footage—we handle the rest. You can use our calculators, the Siding and Paneling Square Foot Calculator or the Reclaimed Wood Flooring Calculator for Square Feet to make your square feet calculations.

Does this calculator factor in material waste?

No, this calculator does not factor in material waste. It calculates precise square footage based on linear length and board width. For material planning, we recommend ordering an overage by increasing your total square footage by 10–15% to allow for cuts, defects, or irregular edges.

Is this calculator compatible with all siding profiles?

Yes, this linear feet to square feet calculator is compatible with all siding profiles. Whether you're using shiplap, T&G, straight edge, or board and batten, the calculator works as long as you enter the correct board width. It’s built for flexibility across all our siding and paneling types

Can I use this calculator for reclaimed paneling inside my home?
