# FAQ: How To Use A Level On A Wall?

## How do you put a level line on a wall?

If you need to make a long, level line (or a plumb line) and don’t own a laser, try this method. Mark the desired height of your line on the wall. Hold your plumbers level at the mark and adjust it until the bubble is centered. Then make a mark at the opposite end of the level (Photo 1).

## Where should the bubble be on a level?

The bubble in the center of every vial (if there is more than one) should be centered between the two level indication line marks. If the bubble is centered, the surface you are checking is level. If the bubble is off center, then your surface will be rising up to the side that the bubble is higher on.

## How do you make a straight line using as levels?

Place the level on a flat surface or object and turn it on. Or optionally hold it in your hand at a prescribed measurement on the wall. The laser beam will indicate a straight line.

How to Use a Line Level to Level Ground

1. Find a length of string and two wooden stakes.
2. Tie one end of string to a wooden stake and hammer it into the ground at the highest elevation in the area.
3. Hammer in the second stake across the area you want leveled.

## What are the 3 bubbles on a level?

Some levels also have a third vial which allows you to find a 45 degree angle too. On each vial there are two marks that are spaced apart. When the bubble sits between them it indicates a horizontal or vertical level (or 45 degree if you are using the third diagonal vial).

## How accurate is a bubble level?

Accuracy – a bubble level is only as good as its ability to give you a truly level measurement. We prefer to use levels with 0.0005″/1″ accuracy or better. On a 48″ level, that gives us a maximum error of +/- 0.024″, or 3/125″.

## Is a longer level more accurate?

Two things to keep in mind: the longer the level, the greater the accuracy — and that when working in cramped quarters, an overlong level is useless. So having a nine-inch torpedo level in your kit is probably a good idea. There are smaller one, too, as short as an inch in length.

## How do I know if my yard is level?

You can determine whether the string is level by laying a carpenter’s level on the string and raising or lowering the string so that the bubble appears within the grooves on the level. Now measure the distance from where the string attaches at the far stake to the ground.

## How do I make sure the ground is level?

If you are leveling a small area, you can tamp the soil using your foot and the bottom of your rake. If you are leveling a large area, or it is especially important to keep the ground level (such as if you are building a structure), get a tamper or plate compactor to compact the soil. Let it settle.
