The person who first said “measure twice and cut once” must have been intimately familiar with the distractions on a busy project site. It’s easy to make a mistake while measuring and marking lumber because of the constant switching between measuring tape, pencil, square, and saw. That’s exactly why the Kiwi Vision Morgan Square was invented, and why I decided to test one.
The Morgan Square was designed to turn measuring and marking into a one-step process by connecting the square and tape measure into a single unit. The square has tabs and slots that allow the user to physically connect their tape measure to the square so they’re not trying to manage two tools and a workpiece at the same time. To assemble the Morgan Square, insert the tape tab on the blade into the belt clip on the measuring tape, then extend the tape beneath a tab marked “CL” (center line) and allow the hook to rest over the edge of the tongue. There is also a slot to hold a pencil below the tape.

Innovative Measuring Tool

Kiwi Vision Morgan Square
Several key design features make the Morgan Square uniquely helpful. The one I tested was made of anodized aluminum with laser-etched markings for durability, though plastic models are also available. The measurements are shown in both imperial and metric, so there’s no need to convert measurements based on preference. The tongue is 1½ inches wide, and the stud center line (CL) is clearly marked over the tape. To assist with wall opening layouts, there is a reference mark on the blade 1½ inches from the inside edge of the tongue to indicate the position of a king stud, trimmer, or cripple stud.
The brand claims that this setup improves measuring accuracy and reduces project time, and I believe that it does. It was easy to use, and there really was no learning curve. For framing, I could pull the tape and square from an edge, align the correct measurement under the “CL”, and scribe lines down both sides of the tongue. Normally, moving back and forth between the cutting station and the project, it’s easy to put down the tape or pencil and walk back without it, then waste time looking for the tools or remeasuring. I never did that when I was using the Morgan Square; the convenience of having the pieces attached made for a cleaner process.
The only downside was that my carpenter pencils were too thick to fit the pencil slot, so I shaved the paint off one. Keeping these three tools together all the time made the job progress noticeably smoother than normal. The Morgan Square is available in both 8-by-8-inch and 8-by-12-inch sizes and works with most tape measures.
