The SkyCiv floor joist span calculator allows you to calculate the maximum span of timber joints. The calculations in this tool are based on the American Wood Council's standards. The floor joist calculator considers factors including the joist size, πάχος, ύψος, wood type, and wood grade as well as loading and deflection factors. Various common types of wood and grades are available within the below floor joist spacing calculator.

## Συχνές ερωτήσεις

### What is a floor joist?

A floor joist is a member that supports the weight of a floor and loads placed on a floor. These are horizontal structural members that are found parallel to the ground and help distribute the weight to the underlying structural foundations. Flooring joists are vital to the stability and strength of a floor structure. The above flooring joist calculator can be used to determine the appropriate size of joists depending on loading and other factors.

### What is a floor joist span table?

Floor joist span tables are references used by engineers, builders, and construction workers to estimate the appropriate size of joists based on factors such as the joist parameters and floor loading. The above floor joist calculator can be used in place of a floor joist span table.

### How does on-center spacing affect floor joists' maximum span?

The on-center spacing is the spacing between each joist. Γενικά, the larger the spacing (distance between each joist) then the lower the maximum allowable span is.

### Do floor joist span tables and calculators work for wood like LVL (Ξυλεία από πλαστικοποιημένο καπλαμά)?

Floor joist span calculators and tables can be used for LVL timber as long as considerations around the material properties and behavior of the lumber are taken into account.

### Do floor joist span calculators and tables work for deck joists as well?

Ναί, floor joist span calculators and tables can be used for deck design as long as all considerations are taken into account.

### Can floor joist tables be used to calculate the maximum allowable span for timber floor joists?

Ναί, floor joist tables are generally available for timber floor joists. The correct table needs to be used based on the type of wood, lumber, or timber joist. Εναλλακτικά, the above floor joist spacing calculator contains options for many types of wood including:

• Alaska Yellow Cedar
• Aspen
• Baldcypress
• Beech-Birch-Hickory
• Coast Sitka Spruce
