Double Square vs Combination Square: The Differences
Correct measurements are crucial for any design work. To achieve that workers use different instruments.
The square is such an instrument. It helps in making the correct angles. There are two types of squares available in the market. It’s not easy to choose between them.
So, which one is the best between double square vs combination square?
Well, the answer is not simple. Both these squares are very helpful in making correct measurements. However, the two faces in the double square are the same. Whereas combination squares have two different faces. Again, the double square has a smaller blade size and the other one has a bigger size.
Anyway, this is only a small portion of my discussion. A lot of information is yet to be unveiled. So please keep reading!

Short Comparison
To get the best use of squares one has to use the accurate ones. So the user must have a clear idea of the specs and use of them. Woodpeckers’ combination square and double square have many similarities and dissimilarities. To choose the best one you have to invest enough time.
However, I am here to make your work easy. Observe the following table to know about double square vs combination square.
| Factors | Double Square | Combination Square |
| Face Types | Same Face Both Sides | Different Face |
| Angle Measured | Only 90 Degree | 45 and 90 Degree |
| Blade Size | Smaller | Bigger |
| Best For | Machinist Works | Wood Works |
| Versatility | Less | More |
| Price | Check on Amazon | Check on Amazon |
You can make your decision easily from the above table. And if you want to know more, I will help you. In the next sections, I will discuss this topic in detail. Please keep scrolling!
Extended Comparison
Best double square and best combination square have their qualities. I have tried to compare their basic differences in this discussion. I am sure that you will not be disappointed!
Face Types
The basic difference between these two squares is the number of face types. The face is the most important feature of the squares. Squares are used to determine right angles. And face plays a very significant role in this work. It is used as the frame.
In a double square, two straight faces are available on the two sides. Because of these two same faces, this square is known as the double square. Any of the faces can be used as the reference frame. So angles can be measured from any side of the scale.
On the contrary, the combination square comes with one straight face. The other face is not parallel to the straight face. So in this square, only one face is used for a right angle. However, the other face has different advantages.
Angle Measured
Another important aspect of the squares is the angle measured with them. The right angle is the most commonly measured. So squares emphasize measuring this angle. However, the 45-degree measure is not less important. It has various uses too.
The double square can measure only 90 Degrees. Because it comes with flat faces only. To measure 45 degrees the square must have a 45-degree incline. The combination square is upgraded in this factor.
It has an inclined face along with a straight face. So it can measure both 45 degrees and 90 degrees.
Blade Size
The blade size of the squares determines the sizes it can measure. With big squares, bigger lengths can be measured at a time. However, on many occasions, the user needs a smaller blade. The blade size plays an important role in maintaining accuracy.
The blade size of the combination square set is usually bigger than the double square set. Because of its straight blade, it has a longer usable length. However, this length is variable. That means you can buy different lengths of squares.
Woodworking rulers are needed to measure the correct lengths. I have some suggestions for that.
These are the best products on the market. You will surely love them!
The traditional length of the combination and double is six inches. But for more functions extended lengths of squares are made nowadays. 12 inches and 18 inches double and combination squares are available in the market.
Best for
There are different functions of squares. They are used for making straight lines without any error. Squares are also essential in making holes.
So they are equally used for measuring wood and different machine elements and parts.
The double squares are best for machinist works. Various metal pieces are measured easily by using this square. The alignment of the metal pieces can be kept straight using this square.
Anyway, this does not mean that double squares are useless in woodworks.
Similarly, the Woodpecker combination square also has its specialization. It is an excellent choice for woodwork. The cutting and boring of woods are done easily with this square. However, the combination square is also useful in other machine works.
Versatility
Now let’s talk about the versatility of these two squares. Versatility means how widely the squares can be used. This can be important for many users. Because when a square is more versatile it becomes more useful.
In this aspect, the combination square leads the race. It has more usability because of its two faces. Combination squares are very functional in both wood and machine works. It is widely used by hand tools workers.
The double square is less versatile. But it is also preferred by many workers. So choosing the square is very much dependent on the work type.
Price
I have reached the end of my comparison. I will talk about the price factor of the two squares now. Price is a determining factor for many buyers. So it is crucial to discuss the cost.
You don’t have to think much about the cost of the indexable combination & double squares. Because the price of the squares is not so indifferent. They come at a similar cost. You will get a basic double square for a cost of $25.
And a basic combination square is available for $30. So the prices are very similar. However, you can buy more lengthy and high-end squares. They will cost more than the basic price.
This is the end of the comparison between double square and combination square. Now you have to make your decision. If you are still in doubt, scroll to the next section. I will present my views on this matter there.
Final Verdict
Selecting the correct square for you depends on your workload. The budget is quite negligible here. So you have to be sure about the intensity and type of work you will be doing.
For any use, a combination square will be better. Because it has more versatility and usability. You will be able to use the combination square in many fields of work. But you must buy the correct size for yourself.
Anyway, if you have any special requirements, you will need the double square. And once again be careful about the size. If you can afford an increased budget, I would suggest you get both of them.
FAQs
What is a square combination?
A square combination is an upgraded version of a double square. In a double square, only 90 degrees or right angles are measured. But this is not enough for all types of work. So the combination square was developed. It has two types of faces. It can measure two angles, 45 and 90 degree angles.
What is another name for a combination square?
Another name for a combination square is an adjustable square. It can be adjusted according to needs. To adjust the screws on the blade are loosened. Then the handle can move along. It can be adjusted on the blade again by tightening. Because of this, it is also known as an adjustable square.
How are squares used in engineering?
Squares are very important in the field of engineering. Engineers design various workpieces according to needs. To successfully design any part, correct designs are a must. And the squares come in handy to achieve the correct design. Without proper measurements, engineering would become hard.
Conclusion
This is all I have on double square vs combination square. I think that now you can make the correct decision. Think wisely and then decide.
