Everyone knows it – the folding rule

A folding rule has many names. There are for example: folding rule, folding meter, ruler, scale, measuring rod, measuring rod, meter, metre rule, metre rule, metre tape, bevel, centimetre, centimetre rule, zolli, inch rule, double metre (Switzerland), folding meter, and cubit.
But how did the folding rule get its name and what can it actually do?

All this and even more we clarify now!

Why the folding rule is called folding rule

“Zoll” like Zollstock originally comes from Middle High German. There it was written “Zol”, which meant as much as a cut piece of wood. It used to be customary to use cut pieces of wood to measure something.
Your own body served as a guide. For example, the piece of wood was as long as the thumb was wide, or as long as part of the foot. The cubit was not spared either.

In former times the thumb served as a guide. A cut piece of wood was as long as a thumb wide.

To be able to imagine this better: One inch was the twelfth part of the foot. The piece of wood was divided into twelve sections and the folding rule was finished. A wooden stick the length of one foot. It can be assumed that the first precursors of today’s folding rule were made here.
At some point this way of measuring became too imprecise, as it is known today that not every human being has feet of the same size. So humans were forced to agree on more exact units of measurement. So they agreed that one inch should be exactly 2.54 centimeters long.

And who is wondering now …

Today we no longer measure in inches, but in centimeters and meters. As a result, the folding rule, also known as the metre rule, was created. Meanwhile the good pieces are made of wood, aluminium and plastic. Some plastic folding rulers are even reinforced due to their advantages, for example with glass fibre parts.

There are folding rulers made of wood, aluminium and plastic. Here you can see a plastic folding rule from the Kunststoffwerk in Buchs.

How do I know which is the best folding rule for me?

Having the wrong folding rule is a bit like wearing the wrong shoe. It simply does not fit and cannot be made to fit. You can’t find a denominator. This makes it all the more important to seek competent advice when choosing a folding rule. Depending on which industry you come from, it makes little sense to buy a wooden measuring stick. Because: Where a lot is worked with water or chemicals, for example paints, one need not be surprised at the end if the edges of the new folding rule swell up or one can hardly read the scale from the desperate attempt to scrub off the paint. Annoyingly it doesn’t come close here! And again you can look around for a new companion.

What is worth paying attention to when buying?

How robust and durable a folding rule is depends on the production of it. For example, if you don’t know where the folding rule comes from, you can’t be sure of its quality. And especially in the quality of a folding rule there are numerous differences. So, be sure to pay attention to the quality of your future faithful companion. If you are unsure about the quality of your folding rule, you should ask for competent advice. The joints also play an elementary role in the folding rule. You don’t find any fun in a joint that is worn out and / or even rusts after half a year. The joints are, so to speak, the main component of a folding rule, because only these hold the individual links together reliably.

When buying a folding ruler, make sure that it is of good quality so that you avoid rusting and too rapid a wear of the accuracy.

When buying a folding ruler, make sure that it is of good quality so that you avoid rusting and too rapid a wear of the accuracy.To catch a glimpse of the accuracy class is no mistake here either. The minimum requirement for the EC accuracy class is III, where I is the most accurate class. If you have ever used a folding rule, you certainly know that it can sometimes be quite useful. In order for you to get the most out of your folding rule for a long time, we also recommend to pay attention to a high elongation at break in order to bring the stability to a maximum. Additional benefits include metal ends or returning scales for reading from both sides.

Can today’s folding rules do more than just measure?

Over time, people, the world and nature evolved. So the basic features of the folding rule naturally continued to progress. Nowadays there is nothing that does not exist. The practical all-rounders are now available in a wide variety of variations. For example, there would be a folding rule with a sliding depth gauge to measure holes.

This not only provides those who use it daily with valuable time, but also saves them cumbersome work steps. It is rather rare to find an integrated angle scale in a folding rule. Especially in professions where you often drill once and join parts together, this represents an absolute added value. But you cannot only measure straight distances and corners with folding rules for a long time! A circumference meter can also help with a round object. And so you will find the right folding rule for almost every special field.

You can find circumference meters, protractors, etc. in our assortment! Our folding rulers consist exclusively of plastic with glass fibre components.
