Range is the wrong thing to shop for here. A hundred feet covers almost every residential interior in the country. What decides this is seconds per room, whether you can work it one handed while holding a clipboard, and whether the number gets out of the building without being copied by hand.

Where a listing does not publish a working range, this table says so rather than guessing. On budget units the rated figure is an indoor matte target number anyway.
That is what makes this different from every other page on this site. A contractor measures whatever is in front of them. An appraiser measures a three bed ranch, then another three bed ranch, then a colonial, and the tool is used the same way in every one. Small inefficiencies compound across a working week in a way they never do on a single job.
Which means the specification that matters is not range and not tolerance. It is how many seconds it takes from walking into a room to having a usable number, and how many times you have to put something down to get it.
A residential appraiser reviewing the Bosch GLM400CL made this point better than any spec sheet could. They rated the tool as getting the job done, then listed what annoyed them: it takes noticeably longer to acquire a reading than the Leica they had before, which matters when a dog is barking at your hand, and they never got the add and subtract functions working, which made their field sketches busier and slower. None of that is visible when you compare the boxes.
There are three workflows here and they want different tools.
Read and write. You take a number and put it on a paper sketch. Almost any unit here does this well and the cheap ones are perfectly adequate. Buy for a bright display and one handed operation, and spend the money you saved on a second unit.
Transfer. The number goes into your phone so it cannot be misread later. This is where Bluetooth earns its price, but only if the app works on your phone. Two units in this guide have documented platform problems, covered below.
Sketch. The app builds a floor plan while you walk the house and you leave with something you can attach to a report. This is a much bigger ask of the software and it is effectively a Leica decision at this price level.
Owners of the Bosch GLM400CL report that it will occasionally show the previous measurement as though it were a new one, instead of showing a failed read. On a job site a wrong number gets caught when the piece does not fit. In an appraisal it goes into a document somebody relies on and nothing catches it. If a reading appears instantly and looks like the last room you measured, take it again.
If you are measuring to report finished square footage, the ANSI Z765 standard measures to the outside face of exterior walls, and reports above grade and below grade areas separately. A laser measure works from inside the room, which means every exterior dimension you take is short by the thickness of two walls unless you account for it.
No unit on this page fixes that. What some of them do is make it less painful. Units with an add function let you build the wall allowance into the measurement as you go rather than adjusting afterwards. Units with poor or unintuitive arithmetic, which is a specific complaint about the DEWALT and the Bosch outdoor unit, push that work back onto your sketch.
The alternative is to measure the exterior perimeter directly, which is faster and standard compliant but needs a unit that works outdoors in daylight. Almost nothing on this page does. That is a separate guide and if exterior measurement is most of your day, start there instead.
The only unit at this price whose app produces a floor plan worth attaching to a report. Buy it for the software, because the hardware is deliberately modest and 120 ft is more than any house needs.
Right for: agents and appraisers who want to leave the property with a drawing rather than a page of numbers.

Right for: anyone running a paper or tablet sketch rather than an app driven workflow.

Right for: appraisers on estate and multi family work, and anyone measuring long hallways or open plans.

Right for: Android carrying inspectors and agents who want transfer rather than sketching.

Right for: agents who need a reliable interior tool and do not want to think about it.

Right for: agents who want green beam visibility indoors and treat the app as a bonus rather than a workflow.

Check price on AmazonHere for a specific reason. This job loses tools in vacant houses, and two units for twenty dollars means a dead battery never costs you a return visit.
Right for: keeping one in the car and one in the bag, as insurance rather than as a primary tool.

Right for: quick room checks and showings, as a companion to a primary unit.

Check price on AmazonIf you want to walk out of a property with a floor plan, buy the Leica D1 and accept that its hardware is unremarkable. You are paying for the app and it is the only app at this price that does the job properly.
If you sketch on paper or on a tablet, the Bosch GLM100-23 is the better tool and it costs less. Speed to a reading is the specification that saves you time in this work, and Bosch is quick.
If you carry an iPhone, do not buy the DEWALT for its Bluetooth. Multiple owners report it simply does not connect, and there is no fix on your side.
And whatever you buy, buy two if you can. This job leaves tools in vacant houses.
Two things slow appraisers and agents down more than any specification, and both are avoidable.
The first is arithmetic in the field. If you are adding wall thicknesses or summing runs in your head, the tool should be doing it. Units where owners could not work out the add and subtract functions are costing you time on every property, and that complaint shows up against both the DEWALT and the Bosch outdoor unit.
The second is transcription. Every number copied by hand is a number that can be copied wrong, and in this work a transcription error ends up in a document. If that risk matters to you, it is worth paying for a unit that records rather than displays.
Before the first property, check whatever you buy against a known length. It takes five minutes and it is the only way to know your particular unit holds its specification.
If none of the above is quite right, the eight we recommend most often are on our front page.
