Joist Calculators

Floor Joist Count: Computes the number of joists (joists and end plates) and joist ties required for a floor or deck based on the dimension of the room or deck and the on-center joist separation.
Floor Joist Cost: Estimates the cost of Floor Joist boards (joists and end plates) required for a floor or deck based on the dimensions of the deck, spacing of joists and unit cost of joist boards.
Joist Hanger Count: Computes the number of joist hangers required for a deck based on the width of the deck and the spacing of joists.
I-Joist Count: Computes the the number of I-Joist boards required to cover a span (width) based on the size of the span and spacing of the I-Joists.
Maximum Joist Span: Computes the span length of a (1,200 pounds per square inch fiber stress) wood joist based on the live load, spacing, board width (e.g., 2x6 vs 2x10) and whether the joist need to be extra stiff for materials attached such as plaster below them.
Joists on Beams: Computes the number of joists (2x dimensional lumber or i-joists), number of beams, number of joist hangers, and length of plate boards needed for a floor or deck with a span that might require one or more beams.

2x6 Price Survey

The 2x6 Lumber Pricing table contains recent lumber prices for 2x6 of a variety of lengths with prices from Lowes, Home Depot, Menards and potentially other stores based on their web sites.

This table is a repository of pricing data for common lumber (2x6's) as surveyed from the websites of major lumber retailers in the United States.

2x6 price survey:

2x6 Price Survey Date: 4/10/24
2x6 Price Survey Store: Menards
2x6 Price by Length
- Price of an 8' 2x6: $6.98
- Price of a 10' 2x6: $10.53
- Price of a 12' 2x6: $11.52
- Price of a 16' 2x6: $14.62

All prices are in U.S. dollars and based on searches of nationally advertised prices from the provider's web sites. Search string: "kiln dried 2x6 lumber" is used in the retailer's website. The term two by six (2x6) refers to the rough cut dimensions of construction grade lumber. However, the typical 2x6 purchased at a lumber yard is actually `1 3/4`" x `5 1/2`". Nonetheless, the term 2x6 persists. These values can be used in the Stud Framing Calculator and the Joist Framing Calculator.

NOTE: Local pricing should ALWAYS, ALWAYS, ALWAYS be used! These price points are for estimation convenience only, and there is no guarantee on the prices of the product nor of their availability at the stated price.
