Laser Level Buying Guide 

Whether you are a contractor, handyman, or just a homeowner that enjoys tackling projects around the house, you will likely find yourself in need of a laser level. There is a wide variety of styles out there that are designed for a variety of purposes, but the one thing they all have in common is the ability to make your life easier. This guide is designed to go over the uses of a laser level, the types on the market, things to look for, and some of the accessories you can purchase to use with it.

What is a Laser Level?

Simply put, a laser level is a tool designed to help you quickly lay out a project. There are many applications for using one both indoors or outdoors. Unlike a simple spirit level, also known as a bubble level, a laser level can work over great spans. It also serves additional purposes, such as measuring distances.

When used indoors, a laser level is great for a variety of decorative and building purposes. It can help you hang shelves, pictures, and mirrors. If you are constructing a building, they are great for checking the height and spacing for doors and windows. Additionally, you can align your shelves, trims, and cabinetry.

As for outdoor uses, they are great for determining how level a plot of land is. You can also use one to help you lay out a site and plan on where to lay plumbing pipes quickly and accurately.

Due to the wide variety of uses, a laser level is a must-have tool for both the home and construction sites. It is a great time and space saver to add to your toolbox. Below are the different types of laser levels available on the market today.

Cross Line Lasers

These work by projecting both a vertical and horizontal line. They are most commonly used indoors. The range of use depends greatly on the quality of the level. Here are some of the situations a line laser would be useful when inside:

  • When fitting tiles onto walls, such as for a kitchen back-splash
  • To install a drop ceiling
  • When installing a partition wall
  • When installing new plumbing or electrical system
  • For framing a new room
  • Installing cabinets and countertops

Although more often thought of as a level for indoor use, a cross line laser level can be used outdoors in these scenarios:

  • Alignment of concrete forms before building on them
  • Building a deck in your yard
  • Making sure any digging you have done is level

When using a laser line level outdoors, you will likely need a Line Laser Detector. Due to the bright conditions caused by the sun, it can be difficult to see the laser outdoors. The detector, which will be discussed in more detail in the accessories section, can help get around that.

Single Line Lasers

These are the absolute simplest laser levels on the market and are almost always the cheapest. They are used manually. Once you have set them perfectly level, you simply switch them on and they then project a straight line. Generally, it only will project a few feet.

If only needed for occasional, simple jobs, this may be the best laser level for home use. You can use one to tape off paint lines or hang mirrors and artwork.

Dot Lasers

These are another popular type of levels, but the uses are more limited. Although they are similar to a line laser, they project a dot, or multiple dots, rather than a full line. They are immensely useful for determining angles. Plumbers find them particularly handy for installing piping. Here are some things you might find one practical for:

  • Installing level electrical sockets
  • Hanging up heating conduits
  • Laying out any pipe or duct-work
  • Installing ceiling lights, particularly if doing so in rows
  • Hanging shelves or cupboards in the corner of a room

Flooring Lasers

Even though this product has a somewhat limited use, it is an incredibly important one. Before laying down a floor, you need to ensure that there are no irregularities. You will almost always use one of these levels indoors.

On top of being useful before laying a new floor, these can be handy for seeing if an uneven floor is causing other problems in your home. It can also be used to install a heating system under the floor.

Rotary Lasers

This handy tool is designed to check the level of an entire room at one time. They are generally heavier, larger, and much more expensive than line lasers. We have talked in great detail about the recommended rotary laser levels.

Factors to Consider

When deciding what laser level is the correct one for you, you need to ask yourself the following questions:

1.) Are you going to be using your level primarily indoors or outdoors? Although there are some exceptions, line lasers are generally considered the best for indoor use and rotary lasers are considered the best for outdoor use.

2.) Do you want a manual or automatic one? With a manual laser, you set them up yourself. If you do it correctly, it can be completely accurate. An automatic laser will be quicker to use and does all of the work for you. They are generally more expensive. One of the best things about an automatic level is it will stop projecting if it is bumped, preventing inaccuracies in your work. A manual level will not have this ability and will need to be monitored to make sure it has not been moved.

3.) Would you prefer a green beam or a red one? The differences here are quite simple. A green laser is much easier to see but much more expensive to produce. Generally, the will only be used on a large indoor project. With an outdoor project requiring a long range, using a laser level detector is much more practical.

4.) How do you want your laser level to be powered? This may not seem like a huge deal, but it is worth considering, especially if you are shopping for a laser level for builders. Most laser levels on the market today use standards alkaline batteries. Usually, they are AA but you will occasionally find ones needing D batteries. Hauling around extra D batteries may not be something you want to do, so be sure to look into the expected battery life. There are some on the market that use a rechargeable OEM battery pack. You can even find some that have 120V AC Power, but that is rare.

Range Requirements

On top of the above considerations, one of the most important factors in your laser level buying is determining the range you will need to use it in. If you are using a laser level for framing or other construction, ask yourself how big your typical job site is.

It is also worthwhile to consider what the biggest job site you will ever need to use your laser level on is. A single line laser typically has a range of 10-25 feet. A cross line laser typically has a range of 25-100 feet. Both of these products can be boosted with a sensor.

The exact range will vary from product to product. If you are unsure how long of a range you need, it is always better to overestimate rather than underestimate.

Accuracy Requirements

Obviously, no one wants an inaccurate level. There are some jobs where 100% accuracy is more important than others. If you are being paid to create custom cabinetry or cupboards, you will need to be precise.

On the other hand, if you are constructing a dog or tree house in your own backyard, being off a quarter of an inch or so won’t really matter.

A laser may require some maintenance to stay accurate. Some come with a built-in calibration feature that you need to run occasionally. Others actually require being taken into a shop to be calibrated. Depending on how much accuracy you need, selecting a level with a calibration option may be important.

Ultimately, the level of accuracy you get with your level depends on how much you are willing to spend on it. A cheap single line laser can be off a half inch when you get out 10 feet. A cross line laser is going to be more accurate, as well as more expensive.

Usability

Some people like high-tech gadgets with all of the bells and whistles. Some people need straightforward tools that won’t have them looking for the user’s manual. If you don’t like using your level, you most likely won’t be satisfied with your purchase.

There are several fancy features you can look for, such as self-leveling, battery level indicator, out-of-level indicator, and the ability to customize slopes and angles. As with everything, the more complicated it is, the more expensive it will likely be.

Durability

Construction sites, whether you are working outside or in your own home, can be rough. Due to the sensitivity of the job it does, a laser level can be rather fragile. Many will claim to be able to withstand a drop of 3 feet, but it is better to not test that theory.

The warranty that comes with your level should be a major consideration. They can range anywhere from 2 to 20 years. Depending on how tough you are on your tools, you may need something with a more comprehensive warranty.

If you will be exposing your level to harsh conditions, such as rain, dust, mud, or other junk, you may need to get one with an IP-rated enclosure. IP stands for “ingress protection.” It is a universal scale to tell the consumer how well an enclosure will keep out both solid and liquid particles. For solid particles, the scale ranges from 0 (no protection) to 6 (entirely protected.) For liquids, the scale is slightly more complicated. It ranges from 0 (no protection) to 9k (2 minutes 80° C at 8-10 MPa). If your enclosure says IP24, the 2 refers to solid particles and the 4 refers to liquids.

Accessories

There are several additional items you can buy to make your laser level even more useful. Here is a quick summary:

Laser Line Detector: If your level has a pulse mode, this device can help extend your range and visibility when in bright conditions. Some lasers can have their ranges tripled by these detectors. Not all lasers can use a detector, so be sure to check the specifications of the one you are considering. They can even use acoustic or optical alerts to help you find your line.

Tripod: A great tool for using in conjunction with your laser, this allows you to place it in a sturdy and level place. It keeps your level from moving side to side or up and down. There are two different types – a fixed leg tripod and an adjustable leg tripod. An adjustable one is more useful when you are outside and may need to place it on uneven ground.

Remote Control: If you need to adjust your auto or manual leveling from a distance, a remote will allow you to keep doing what you need to do.

Safety Considerations

When buying anything new, it is important to consider any potential safety hazards. This is especially true if you will be working around children. Basically, there are three things that can go wrong with a laser level:

1.) Eye Contact: It’s pretty simple – never let a laser make direct contact with your eye. Be sure to watch out not only for yourself but for anyone else around as well. Class 1, 2, and 3 levels are considered to be relatively safe. If your eyes came into contact with these, your blink reflex should kick in before any damage is done. Keep in mind that even these lower level lasers can do severe damage after just 0.25 seconds. Another thing to keep in mind is you should never look at the laser through a magnifying glass or pair of binoculars.

2.) Skin Contact: Although this is not a major issue when laser levels are properly used, bear in mind that lasers work using radiation – either infrared or ultraviolet light. For most commercially available lasers, the danger is minimal. Some of the higher level 3 lasers can cause skin burns after prolonged exposure.

3.) Fire Danger: This is another thing that only becomes a serious consideration with high-end level 3 lasers. If allowed to point at a combustible or flammable object for a prolonged period of time, it can ignite it.

Conclusion

Having the right laser level is essential to do a high-quality job. Without an accurate one, measuring can become monotonous and may end up being inaccurate. Considering how many applications a laser level can have, it is no wonder the market has so many different options.

Hopefully, this guide has helped you to determine the best laser level for your needs, whether you are a seasoned pro or starting out in the DIY world. Ideally, you will find the tool that does everything you need it to without spending money on the things you don’t.
