16" vs. 24" Floor Joist Space | Sound Home Resource Center

The vast majority of floor joist systems are built with 16" OC (on center) spacing. It is possible to build with wider spacing. For example, in the 50's and 60's many homes were built with 4x10 "joists" at 4' OC. However, such construction used 2x6 t&g, or 1 and 1/4 " plywood subfloor material. This was a good system, but very costly with today ...

Can I Install Tile Over My 24" o.c. Floor? - CTaSC.com

This house was built 7 years ago and since I selected a vinyl floor, the builder placed my joist 24 inches on center. The builder has recommended hardwood over tile for the job but thought a 3/8 or ½ inch piece of plywood with Ditra on top would also suffice. My local tile shop is pushing hardy backer.

Stud Spacing for Shed: 16” or 24” on Center – Which is Better?

For sheds with these dimensions or less, 24-inch shed spacing will usually suffice to resist wind load. Even for a shed that is a little larger than normal, a stud spacing of 24-inches might be sufficient. If that is, the bottom plate is anchored to the head and double-joists properly, and you make use of 3-stud corners.

16" o.c. vs. 24" o.c. - Fine Homebuilding

I often go to 19.2" for I-joists and 24" for open web trusses. As to the subfloor deflecting - the wider web truss means there is barely more freespan between joists than with solid wood. unless you have large ceramic floor tiles, it is no concern.

How Far Can You Span a 2X10 Floor Joist? | Hunker

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. Use a joist span table such as those found in the Resources section to determine the maximum 2-by-10 joist spans for other species and lumber grades.

Strength of 2x6" - 24" Center vs 2x6" - 16" center ...

One of the more relevant details is subfloor and floor joists, actually. You want walls to line up with floor joists and roof trusses. 24" OC removes the option of going with the cheapest thinnest floor sheathing (you get deflection between joists), and increases the deflection of the joists themselves, all other things being equal.

Floor Framing & Structure | HomeTips

Normal spacing is 16 inches “on center” (from center to center), though some floors may have joists on 12-inch or 24-inch centers. Joist sizing and spacing are determined by building codes, which are based on engineering requirements. Joist headers run perpendicular to the joists, capping their ends.
