In my user collection of squares I have a new 12” Starrett combination square, an old ~1920’s but still accurate 12” Starrett I think my great grandfather might have taken home from his job at Ford (it’s etched on the blade, with a number), and a similar aged Stanley Sweetheart 6” solid square that’s also still accurate.

The 12” combination square is great for most things but sometimes it’s a little too big. I don’t end up using the 6” square too much. I think I need a smaller combination square or double square. What do you guys find to be the most useful as far as size, the 4” or 6”? Is there any reasons to get a double square vs. a combination square? I can’t see any advantage to the double square but maybe I’m missing something?

I use both a 12” and a 6” Starrett combo and a 3” double.
Double is nice for smaller pieces.

I like the Starrett 4” combo, another in this photo is a 6” flat square.

I use both combination and double squares in 4”,6”,12”, and 24”. I use the 4” more than the rest, I do a lot of small projects. Although I don’t need the 24” often, it’s nice to have when needed. If I had to choose between a combination or double head, I’d go with the combo. I also have multiples of each so once I have one set I don’t have keep changing them.

I use the 12” the most, but also get a lot of use out of a little 4” Starrett double square.

I had a 4” Veritas double square and used it as my go to square until I dropped it and broke the pin that holds the blade in place. I have been living without it since and really do miss the thing. I might go with a Starrett double square of the same size when I get around to replacing it probably once the weather warms up a bit but there is nothing wrong with the Veritas version either.

Now I mostly use a 6” combination square. The thing is ok but it’s a lot bulkier than the double square even though it’s really not that big. I do find the combination head on the 6” isn’t that useful to me as if I need a 45 degree angle I often need the reach of the 12” one anyways. I hardly ever use my 12” combination square as I just don’t need something that big most of the time.

So I guess in order of use I would say for my work. 4” double square, 6” double square, 12” combination square. at which point I might be tempted to just ditch the 4” double square and go with a 6” double square instead. Now that I type this maybe I’ll put off replacing my broken 4” square and get a 6” double square instead.

Hope that helps.

The most used square in my shop is the 4” Veritas double square. It’s in my apron pocket or in my hand all the time. I have a 6” fixed square from Woodpeckers that I reach for a lot, but my 12” Starrett combo square is always close at hand.

I use a 4” double square constantly it is always in my shop apron. I don’t know how I got along without it. I think it is the perfect size for most things.

I use my Starrett square to check the accuracy of my other squares, modifying them if needed. I keep the Starrett safely in a toolbox and use the other squares for woodworking. A 12” Stanley combination square is the most used in my shop.

I’ve got 2 4” starrett double squares that I use all the time, and only go get the 12” off it’s hook on the pegboard when I need a longer line.

6” for me. I have three and I set them for different measurements on the project and keep them set for future use. Occasionally I use my 12” but it is pretty rare.

Richard, I bet if you call LV and ask about a replacement pin, they will send you a new one gratis.

I almost never use use my Starrett combination square since I got a 4” Veritas double square, but I have been working on smaller projects.

For framing I use a 12” combo or speed square, when I’m in my shop I use a 6 and 12” machinist square for marking and a 6” combo along with a marking gauge for mortise, tenon, and shoulder cuts.

It seems the 4” double square is really popular. Any reason why you guys are using that over a 4” combination square? The 45 degree reference face on the combination square head seems like it’s worth a few extra bucks to have. I’ve never owned a double square though so maybe it gets in the way somehow?

I love my 4” double and 12” combo. They pair very well together. I do wish I had one of the tiny engineer squares for checking tails with narrow pin sockets.
