There are different types of spirit levels for different uses:
*Carpenter's level (either wood, aluminium or composite materials)
*Mason's level
*Torpedo level [[File:Tool-level.jpg|thumb|right|Torpedo level]]
*Post level
*Line level
*Engineer's precision level
*Electronic level
*[[Inclinometer]]
*Slip or Skid Indicator
* [[Bull's eye level]]

A spirit level is usually found on the head of [[combination square]]s.

===Carpenter's level===

A traditional carpenter's spirit level looks like a short plank of wood and often has a wide body to ensure stability, and that the surface is being measured correctly. In the middle of the spirit level is a small window where the bubble and the tube is mounted. Two notches (or rings) designate where the bubble should be if the surface is level. Often an indicator for a 45 degree inclination is included.{{cn|date=August 2021}}

A line level is a level designed to hang on a builder's string line. The body of the level incorporates small hooks to allow it to attach and hang from the string line. The body is lightweight, so as not to weigh down the string line, it is also small in size as the string line in effect becomes the body; when the level is hung in the center of the string, each 'leg' of the string line extends the level's plane.

===Engineer's precision levels===
{{Unreferenced section|date=December 2024}}
An engineer's precision level permits leveling items to greater accuracy than a plain spirit level. They are used to level the foundations, or beds of machines to ensure the machine can output workpieces to the accuracy pre-built in the machine.
