  • Gives you several scales on its three sides. This is remarkable!
  • Among the best rulers for professionals
  • Unique matte aluminium finish

Factors to Consider when Buying an Architect’s Scale Ruler

Before ordering that scale ruler, there are a few things that you need to keep in mind. With these pointers, you can be sure to get the product that meets your needs during the duration you desire.

Let's delve in.

1. Material Used

This is one of the primary considerations to make. The material used affects your safety, measuring accuracy, durability, flexibility and ease of use. While plastic rulers offer improved safety, are flexible and light, they fail in sturdiness and durability.

Aluminium drawing and measuring rulers are excellent in offering increased durability and rigorousness. However, they need you to be careful with the edges. They are also quite expensive compared to the plastic ones.

The bamboo made scale rulers are least used. However, they are great as they provide a win-win situation in sturdiness and safety. However, they fail in offering the desired accuracy and precision.

The kind of material used also impacts weight. You'll find plastic rulers to be light-weight than metallic ones. Combined with other factors, the weight will influence the architect's experience in measurements or drawings.

2. Duration of Use

Before pressing that order button, you need to have an estimate of the length of intended use.

This understanding will inform the kind of marking you choose and the material used.

If you are transitioning from a student or beginner to a professional architect, we would recommend an aluminium ruler with laser-etched marking. With this, you are guaranteed increased accuracy and long-lasting operation.

Since laser-etched markings are quite costly, if you are constrained financially, you can go for the embossed ones. They'll also serve you for a while.

You can get plastic or bamboo as a spare ruler. This can also work well for newbies or kids starting to use measuring or drawing scale rulers.

As you consider the duration of use, don't forget to think about the users - are they professionals or not? For instance, if kids will also be using the ruler to measure or draw, get plastic ones or metallic rulers with a plastic coating on the edges to prevent accidents.

3. The Desired Number of Scales

There is a need to consider what operations of architecture or engineering you'll be using the ruler for. In other words, what kinds of measurements are you looking to achieve? This will inform the scale ruler you choose.

Different brands offer different scales. But the bottom line is, don't go for scales you don't need or you'll barely use.

More scales doesn't translate to a better experience or increased accuracy. Look for quality and ease of use. More scales that are not needful means that you're not getting value for your money.


When you search for the right architectural ruler, look for design and construction that appeals to you, will serve you for the time you desire, will give you ease of use and made from the ideal material. When you take your time to make this decision, you'll be sure to enjoy using the product.

Enjoy your shopping!
