Measuring tools: your best pals on every project

How to choose the best measuring tools

Which measuring tool you need depends on the kind of work you do or want to do. Because there is a wide range of measuring tools, below is an overview of all the possible options.

Spirit level

A spirit level is essential when you want to be absolutely sure that something is truly straight or at a right angle. With a spirit level, you can check horizontal and vertical lines with millimetre precision. When choosing a spirit level, pay attention to the length and the measurement markings.

Ruler

Rulers are classic and dependable measuring tools. Perfect for measuring and marking off short, straight pieces. In metalworking, you often use a steel ruler because of its durability and sharp, precise edges. For wood, a plastic or aluminium ruler is sometimes better, as the material is softer and less likely to scratch. Pay attention to the scale: a clearly engraved scale prevents measuring errors.

Caliper

A caliper, or vernier scale, is used for extremely precise measurements, such as determining inside measurements, outside measurements or depths of parts. For example, you can measure the thickness of a screw very accurately. It is almost impossible to imagine metalworking, model making and detailed work in woodworking and other fields without a vernier scale. There are analogue vernier scales and digital ones. The digital ones are easier to read, but the analogue ones are more robust and don't require any batteries.

Tape measure & folding ruler

Both a tape measure and a folding ruler are used to measure distances, but each has its own advantages. A tape measure is flexible, compact and quick to use; ideal for quickly measuring long objects such as shelves. The folding ruler is more rigid and unfolds in segments. It stays straight by itself, which is useful when measuring vertical pieces or hard-to-reach areas. For coarse woodworking or construction jobs, a folding ruler is often very convenient.

Compass

A compass is the perfect tool for inscribing circles or arcs. It can also be used as a tool to mark out distances. In wood and metalworking, you often use adjustable or solid steel compasses for precise work. Some compasses are equipped with a lock for fixed radius, which is ideal for repeating tasks.

Try square

A try square is used for marking and checking 90° angles on pieces of wood or metal. Especially when making joints or checking cuts, a try square is essential. Choose a steel or aluminium version with a clear, indented scale for extra precision.

Bevel gauge

A bevel gauge, also known as a sliding T bevel, is and adjustable gauge for setting and transferring angles between 0° and 180°. A try square is stuck on those 90°, but a bevel gauge can be adjusted. Perfect for making angled joints or checking mitre cuts. The adjustable arm is securely fixed with a screw, so you can set and reproduce exact angles.

Angle meter

An angle meter or angle gauge is perfect for measuring and transferring exact angles, for example for window frames, stairs or roof structures. Digital angle meters display exact degrees on a screen, while analogue versions often work with a scale. Choose the type that suits your project and preference. The more precise the readout, the less chance of errors when cutting or milling.

Mitre square

The mitre square looks like a try square, but is specially designed for marking off fixed angles such as 45°. Perfect for making mitre joints for picture frames or skirting boards. Mitre squares are often made of sturdy metal or plastic and fitted with a handle that clamps your project. It's a small but very useful measuring tool for anyone who wants to work with a 45° angles.
