Accuracy Matters With Measuring
Metal and cloth measuring tapes are accurate when used as intended but they aren't always totally reliable. The tapes are fabricated and calibrated for being read at particular temperatures, humidity and at a particular tape tension. Have you ever tried making a vertical measurement with a tape measure? The best digital distance measuring device is accurate to within decimals of a millimetre.
The Best Digital Distance Measuring Device Gives Top Bang For Buck
You can get good results from any measuring tape. The most common tape measure is one of those easy to use 3 meters to 5 meters metal retractable tapes. That sort of tape is marked in meters and millimetres along its length.
These metal or fibre tapes are OK for short distance measurements up to the distance capability of this tape and retraction device. This works if the measurement can be a simple single-handed application or you have a buddy holding the tape's end. It will be a action or operation involving pull, view, measure, note and retract the tape. There is a simpler way.
The best digital distance measuring device or electronic tape measuring device is cheap and suited for simple home projects and uses a simple point and press to measure for all applications; it is quite effective for a simple short distance as well as those complex jobs that require numerous vertical and / or horizontal distances (longer than a 5 m metal tape) to be accurately measured and you can retain the measurements to calculate areas or volumes.
Few small-scale home improvement jobs will need a laser measure with a medium (60m) or long (100m) measuring range capability. Choosing a laser measure with short-range distance measure capability of up to 30 meters that has accuracy to within 2mm for about $45 will be cost effective option for most home-handy workers.
It's often difficult to measure from corner to corner for distances longer than a tape, or in tight and confined spaces, and then there is a need to record, document or remember your measurements if a series of cumulative readings make up a total measurement.
The best digital distance measuring device is a piece of laser measuring technology. A digital distance laser measuring device features built-in horizontal and vertical bubble levels, and it can measure from the front, the back, or from a fold-out end piece of the device, depending on what reference point you need at the time.
The best digital measuring device measures the point to point distance directly to within an accuracy of 1.0mm for professional units and between 1.5mm and 2.5mm for handyman units, then holds the measurements in its memory.
The best digital distance measuring device have a bright and easy-to-read backlit display so you can always get and read accurate measurements in the daylight or in poor light.
The Measuring Job Got Easier By Using A Digital Laser Tape
You might want to add a digital distance laser measuring device to your must have list of tools.
Using a digital distance laser measuring device will enable you to:
- Measure any single line of sight distance (however long within the capability of the laser measure),
- Determine the height of an object or length of wall,
- Calculate distance in metric or imperial units.
- Add or subtract two distances, and
- Use the device while in static or continuous measuring mode.
The laser measure is ideal for home renovators, tradesmen, contractors and professionals in real estate, engineering, construction, renovation, and many other uses.
Laser Features - The Best Digital Distance Measuring Device
Best digital distance measuring device (Laser Measure) is an essential tool; not something people could consider as a ‘nerdy gadget’. Perhaps it is a tool that might get occasional use but there are many tools like that. There are risks of wasting time, doing work twice from using incorrect measurements or wrongly interpreting the hurried notes made in poor handwriting when you were recording the results.
In the building, construction and real estate industries taking an accurate measurement and recording it correctly is a vital task.
The portable laser measure makes that job both easier and faster for amateurs and professionals alike as they use the accuracy of laser light for their measuring and the gadget's memory for retaining the results.
Laser Distance Measuring Devices are also sold under the labels of:
- Electronic Tape Measures
- Laser Distance Finders
- Digital Measuring Devices.
Some models of electronic tape measure have a "Pythagoras feature", which directly calculates the third side of a triangle. That is a feature of a best digital distance measuring device that enables the user to measure direct distances between two points that might be otherwise difficult to access for measuring.
For example, you could stand away from a building wall that you want to measure, point the laser measuring device at one corner of the building and take a measurement. Then turn the device while keeping it's reference end in the same place and point the laser red dot at the other corner of the building and take that measurement.
Using the "Pythagoras feature" button will calculate the distance across the face of the building between the points you marked using the laser pointer. That means, regardless of there being fences and landscaping that prevented access along the building for direct measure. if the points on the building are visible from a separate view point the distance can be determined.
The device calculates the third side of the triangle using geometry. In all measurements, final accuracy is dependent on how well you can actually hold the position of the laser at its pivot position. The device calculates the direct distance between the points marked on the wall being in a flat triangular plane with the device.
The laser distance measuring device’s red dot is pointed at a target such as a wall on a house, a nearly object or whatever, and the device will show the distance between the device and the object on its LCD screen.
You can put the back of the unit against a wall and measure from device to get true wall-to-wall distance measurement. Similarly with measuring floor to ceiling, lay the device on its back with the laser dot pointed up to the ceiling so it measures that distance to the dot from the floor. That has got to be a lot easier than holding a tape at both ends to measure.
The laser measuring devices will display in multiple units of measure, so you can cycle through the units, set and then start taking measurements. Alternatively, after taking a measurement you can cycle through the units of measure and show the record in those units.
There are versatile cost-effective laser type measures available for handy home use or general contractor use for measuring distances from a hand-span up to 160 meters. The more expensive and best digital distance measuring device models used by professionals usually have more powerful lasers, more features, greater range and better accuracy.
The basic technology of laser measuring devices is the same for handyman tools as it is for professional devices. The higher powered laser provides a longer range that are more accurate devices used by professionals, albeit those models have quite advanced features.

Features of Laser Measuring Devices that I Don't Like:
- The four-line backlit LED display screen is not easy to read in sunlight
- The Laser light pointer is hard to see in sunlight or in a very bright room
- Some single short distances are easier taken using a tape measure - the 1.5mm accuracy is fixed even for smaller measurements
Best Digital Distance Measuring Device is Cost Effective:
The laser-measuring device can replace your manual tape measure. The electronic laser tape makes taking measurements accurate, easier, certain and quick. You won’t need helpers or other people to complete a measurement with accuracy: just point and press.
A measurement for say a bridge span needs to be accurate within finite predetermined tolerances. The best fabrication work within a tolerance needs the machine operator or fabricator to trust the numbers so even with this technology you need to be checking each reading twice.
While these electronic tape measures are the best digital measuring devices available you require constant operator vigilance to confirm the recorded measurement spans the intended distance. Use the ‘measure twice / cut once’ strategy to help reduce reading errors from using an incorrect start reference point or finishing measuring point.
To avoid communicating the very accurately measured (but wrong) distance that might arise from referencing error measure in both directions. Even within the device’s fine accuracy tolerance levels where human error is still possible the checked reading will have to be correct in both directions because when one is wrong the measurement has no value.
Measuring Devices: 4 Price Ranges
The challenge of accurately measuring between fixed points increases when you have to measure something that exceeds your arm-span. You can hold only one end of the tape measure, unless there are two people doing this task.
I would choose to buy a laser measure for its ease and accuracy. From the standpoint of the single-handed ability of a digital measure for saving on the cost of a second person, for its portability and convenience, for its simplicity of use and speed of set up, the digital measuring device is the most efficient.
The best digital measuring devices tend to be used in setting out or checking long distances with tight tolerances. In civil engineering works I might use the digital laser measure to provide reassurance by spot checking plans for road layout, confirming bridge spans or set up for prefabricated structural elements in commercial buildings, where the components are large, expensive and complex to modify and reinstall.
The professional devices used there have an accuracy within 1.0mm and their battery is good for up to 5000 measurements between recharges. No worrying about the device failing during a normal day of use.
The digital distance laser measuring device is convenient because one straight line distance figure appears on the device display, accurate to within 1mm, regardless of the distance. You don’t need to hold the tape tight in tension, taking careful note of several intermediate points being in line or remembering anything not immediately written down.
