` = "Ideal Spacing below Max"`

Enter a value for all fields

The **Ideal Spacing below Max** calculator computes the ideal even spacing over a length or distance based an a maximum spacing.

** On Center Uses***Fences**Floor Joists**Wall Studs* *Rebar Mats*

**INSTRUCTIONS:** Choose units, and enter the following:

- (
**L**) Length to be Spanned - (
**MX**) Maximum Spacing

**Ideal Spacing (S):** The calculator returns both the number of objects and their spacing to ideally spread between the end points.

The on center calculation is fairly easy. However, people typically fail to account for the first object. So, if you want to spread 4 posts (n) out to create a fence 24 feet long (L), you can not spread them out where spread = 24 ft/4. This forgets that the first post is at position zero. You a have to reduce the number of posts by one for the first post. In this case, the calculation would be 24 ft/3 (3 = n-1), which 8 ft separation.
