When it comes to DIY projects, accurate measurements are absolutely essential. Whether you’re building a shelving unit, planning a room layout, or hanging picture frames, a small mistake in measurement can lead to big headaches down the line. Traditionally, most DIYers reach for a trusty tape measure, but these days digital laser measuring tools are becoming more common. Should you stick with analogue or upgrade to a digital laser measure? In this post, we’ll compare tape measures and laser measures to help you decide which tool is the best fit for your DIY needs.
What is a Tape Measure?
A tape measure is a classic handheld tool used to measure length. It consists of a rolled strip of marked metal (the “tape”) housed in a compact case. You pull the tape out to span the distance you want to measure, then read the measurement from the markings (usually in millimetres, centimetres, and inches). Tape measures come in various lengths (commonly 3m, 5m, 8m, or longer) and are inexpensive, portable, and simple to use – a staple in every toolbox. Most have a retractable mechanism and a small metal hook at the end that latches onto edges for easy one-person measuring over short spans.
Tape Measures at a Glance
| Pros | Cons |
|---|---|
| • Cheap, tough, no batteries • Wraps around curves & objects • Easy to jot marks directly on material |
• Can sag over long spans • Needs two hands (or a helper) for big distances • Reading scale by eye = human error |

What is a Laser Measure?
A laser measure (also known as a laser distance meter or digital measuring tool) is an electronic device that uses a laser beam to determine distances. It works by emitting a laser light to a target and measuring the time it takes for the reflection to return, calculating the distance almost instantly. The result is shown on a digital screen. Laser measures are typically compact handheld devices as well, and they allow you to measure distances with the push of a button – no tape to stretch out. They are especially useful for long distances or hard-to-reach spots. For example, you can measure the height of a ceiling or the width of a room by yourself with a laser measure, something that can be tricky with a tape measure and no helper.
Laser Measures at a Glance
| Pros | Cons |
|---|---|
| • One‑button readings up to 30 m+ alone • Millimetre accuracy & on‑screen display • Extra functions: area, volume, memory |
• Higher purchase price • Needs batteries/charging • Laser dot harder to see in bright sun |

When to Use Each Tool (Common DIY Tasks)
Choosing between a tape measure and a laser measure often comes down to the task at hand. Here are some common DIY scenarios and which tool might serve you best in each:
- Measuring Room Dimensions: If you’re measuring the length, width, or height of a room (for flooring, paint estimates, or furniture fitting), a laser measure can save you time. You can quickly get wall-to-wall distances and even calculate square footage with a laser. A tape measure will do the job for small rooms, but for large spaces, you might struggle to hold the tape taut alone. The laser measure lets you get accurate room dimensions solo.
- Planning Furniture Layout: For checking if a sofa or wardrobe will fit a space, both tools work. Use a tape measure for simple measurements of furniture and the available floor space. If you want fast confirmation of multiple distances (e.g. spacing between pieces of furniture across a room), the laser measure is very convenient. It allows you to stand in one spot and measure to different walls or between objects quickly.
- Hanging Pictures or Shelves: A tape measure is useful for marking equal distances (e.g. spacing between picture frames, or how far up on the wall to place a shelf bracket). You’ll likely also need a level (spirit level or laser level) to ensure things are perfectly horizontal. This is where digital tools shine: a cross-line laser level can project a straight line across the wall, taking the place of both a tape and a spirit level for alignment. For instance, instead of measuring down from the ceiling at several points with a tape, you could use a laser level (like those in our recommendations) to cast a level line and hang pictures along it. In summary, use the tape measure for distance spacing, and consider a laser level for the leveling part of hanging items.
- Cutting and Building Materials: When you need to measure and mark lengths on lumber, pipes, or other building materials for cutting, a tape measure is usually the go-to. It’s simply easier to hook the end of the tape on the material and mark your cut line at the desired measurement. A laser measure isn’t very helpful for marking a piece of wood, since it can tell you the distance but doesn’t mark it for you. So for tasks like cutting timber to length, measuring for drill hole placements, or any task where you transfer a measurement onto a physical object, the tape measure reigns supreme.
- Outdoor Projects: If you’re measuring out in the garden – say for a fence run or patio dimensions – a laser measure can cover longer distances easily, but bright sunlight can interfere with the laser’s visibility. Many laser devices have a maximum range (which might be reduced outdoors). A tape measure can work outside for shorter spans, but if you’re trying to measure something like 15 or 20 metres of garden by yourself, a laser measure will be far less cumbersome. One compromise some people use for very long distances is measuring in stages with a tape, but with a laser you can get it in one go (just ensure the target surface is something the laser can hit, or use a reflective target plate if provided).
In general, use your tape measure for detail work and close-range tasks, and grab the laser measure for big or repetitive measuring tasks – especially when working alone or dealing with expansive distances.
Quick‑Pick Guide
| DIY Task | Grab This Tool |
|---|---|
| Cut timber to length | Tape |
| Measure whole room for flooring | Laser |
| Hang three pictures in a straight line | Tape + laser level* |
| Set fence posts in a straight run | Laser (use target plate outdoors) |
| Mark drill holes on cabinet | Tape |
Is going digital worth it?
For basic DIY—flat‑pack furniture, short runs, marking cut lines—a cheap, sturdy tape measure is still all you need. If you often work solo on room‑sized jobs or need rapid area/volume read‑outs, a laser measure quickly pays for itself: point, click and you’ve got an accurate figure in seconds, no helper or ladder shuffling required.
The smart toolkit has both: tape for rough‑and‑tumble marking and awkward corners; laser for fast, precise surveys of whole spaces. Add a laser level if you do lots of aligning. Digital tools won’t replace the trusty tape, but they save time and frustration on larger or repeat projects.

FAQ
Q: Can a laser measure replace a tape measure entirely?
Not quite – lasers are faster and better for long, one‑person shots, but you’ll still want a tape for marking cut lines, wrapping round corners, or working in cramped spots.
Q: How accurate are laser measures compared with tapes?
Good lasers stay within about ±1–2 mm at 10 m; a Class II tape is roughly ±2.3 mm and can drift with sag or reading errors, so the laser is usually the steadier bet.
Q: What’s the typical maximum range?
Entry lasers reach 20–30 m, mid‑range 40–50 m, and pro units 100 m +. A DIY tape is normally 8–10 m, so anything longer is far easier with a laser.
Q: Do laser measures work outdoors?
Yes, but bright sunlight reduces beam visibility and range. Pick a model with pulse mode, a receiver, or a green beam, and measure in shade or dull light when you can.
Q: Any maintenance tips?
Tape – keep the blade clean, dry and unbent, and oil the spring if needed. Laser – protect the optics, wipe the lens gently, and remove batteries for long storage. Check either tool’s accuracy now and then.
