In fact, each

**2x10 will**support 1,200 lbs. To be clear, spans are measured as "clear spans".

Herein, how much weight can a floor joist hold?

For example, a **floor joist** at 16” spacing's that **can** carry 53 pounds per linear foot would translate into a 318 pound single point load at its center. Location and configuration of heavy loads should be looked at on a case by case basis.

**40 pounds**per square foot of "live" load (moving weight) or 10 psf "dead" (stationary) load.

Similarly one may ask, how far can you span a 2x10 floor joist?

In general terms, joists spaced 16 **inches** on center can span 1.5 times in **feet** their depth in **inches**. A 2x8 up to 12 **feet**; 2x10 to 15 **feet** and 2x12 to 18 **feet**.

A live load of 60 pounds per square foot demands more **support** and shorter spans. Spaced at 12 inches, the **joist** may only span 16 feet 8 inches. At 16 inch spacing, 15 feet 2 inches and 13 feet 3 inches at 24 inch spacing.
