Spirit Level vs. Laser Level: Which One Should You Use?

Last updated: October 22, 2024

When it comes to construction, DIY or home repair, ensuring that things are straight is critical. Whether hanging a shelf, installing tiles or building a deck, using the appropriate levelling tool can make all the difference. Spirit and laser levels are two of the most commonly used tools for this job. Each has advantages and disadvantages, making them appropriate for various jobs. In this post, we’ll compare spirit and laser levels to help you decide which is best for you.


What is a Spirit Level?

A spirit level, or bubble level, is a conventional tool for determining whether a surface is horizontal or vertical by centring an air bubble in a liquid-filled vial.

Spirit levels, which come in torpedo, I-beam, and box beam models, are inexpensive, portable, and ideal for minor jobs; nevertheless, their accuracy degrades over long distances, and they require a firm surface for dependable readings.

What is a Laser Level?

In contrast, a laser level uses a beam of light to create a precise reference point, making it perfect for large-scale projects and professional buildings.

With options such as dot, line, and rotary lasers, these tools provide exceptional accuracy over extended distances and may be used hands-free. However, laser levels are more expensive, need electricity, and may not be required for simple DIY projects.


Spirit Levels vs Laser Levels

Significant differences exist between spirit levels and laser levels, making each tool more appropriate for different projects. Depending on your individual needs, one may be more advantageous than the other.

FeatureSpirit LevelLaser Level
AccuracySuitable over short distances but less precise for long ones.High accuracy over long distances making it suitable for larger projects.

Spirit Level Tips

How to Use:

  • Place the level on a clean surface and ensure the bubble is centred.
  • Flip the level to double-check accuracy and keep the bubble centred.
  • To get more precise results, use a longer level on larger surfaces.

Mistakes to Avoid:

  • Avoid using a damaged or unclean level as it can reduce accuracy.
  • Don’t use a short level on lengthy surfaces; instead choose an adequate size.
  • Ensure the surface is stable, an unsteady base can result in inaccurate results.

Laser Level Tips

How to Use:

  • Position the laser level on a sturdy surface or tripod to ensure constant accuracy.
  • Position the laser and draw reference lines along the projected beam.
  • Use a laser detector to make the laser line more visible in bright conditions.

Mistakes to Avoid:

  • Always calibrate the laser level before using it to ensure its accuracy.
  • For large jobs, utilise a tripod to avoid instability.
  • To ensure optimal performance, check battery levels regularly and keep the laser clean.

Conclusion

The type and size of the projects you undertake will ultimately determine whether you use a spirit or laser level. A spirit level should be sufficient for simple DIY jobs and small-scale projects. However, if you’re working on larger construction projects, investing in a laser level can provide the accuracy and convenience you require.


FAQs

Can a laser level replace a spirit level entirely?

While laser levels provide more complex functionality, spirit levels are useful for short, quick operations where a laser is unnecessary.

How to maintain and store each type of level properly?

Keep spirit levels dry to prevent rusting, and laser levels in a padded box to safeguard the electronics.

What should I do if the bubble in my spirit level is stuck?

A trapped bubble usually suggests a damaged vial. Avoid using it and consider changing the level to ensure accurate readings if possible.

How far can a laser level project a line?

The range varies by manufacturer, but most laser levels can efficiently project a line for 100 feet or more. Some high-end rotating lasers can project for several hundred feet.
