Measuring is often the first step in a project and accuracy can be vital. Accurate measurements can help you determine project feasibility as well as what materials you need and how much it is going to cost.
There are different measuring tools to use according to your project. Using the right tool will make it quick and easy to get precise measurements.
Tape measure
What: A tape measure is the first tool that everyone thinks of when they need to measure something. They come in various shapes, sizes and lengths to suit a variety of situations and personal preferences.
Why: Tape measures are versatile, easy to use and portable, making them suitable for a wide range of tasks.
Perfect for: General construction, home improvement projects, repairs and restoration, and any task requiring measurement of linear distances.
Tips for selecting and using a tape measure:
- Choose a tape measure with a sturdy case and a lock mechanism to keep the tape extended
- Use the hook at the end of the tape to measure accurately from the edge of an object
- The hook on the tape measure is slightly loose to ensure consistent measurements whether you hook it onto something or push it against something.
Folding ruler
What: Folding rulers are rigid measuring sticks that you can fold into a compact size. When fully opened, they typically extend to a fixed length.
Why: Folding rulers provide rigidity and stability, making them ideal for measuring straight lines on flat surfaces. They excel in tight spaces where a tape measure is too bulky and can serve as temporary spacers by folding to different thicknesses.
Perfect for: Woodworking, carpentry and situations where a straight and stable measuring tool is needed.
Tips for using a folding ruler:
- Many folding rulers are designed to lock at 90 degrees, allowing them to be used as a square
- Folding rulers can lay flat against a surface, allowing for easy marking and measurement, which is particularly useful for tasks requiring precision marking or cutting
- When folded, rulers are compact and easy to store in a toolbox, pocket or work belt, offering portability without the bulk of some tape measures.
Combination square
What: Combination squares are multi-purpose tools with a ruler and a reversible head to suit 90-degree and 45-degree angles. They can include a protractor head and a centre finder head.
Why: Combination squares ares highly versatile for measuring and marking both 90-degree and 45-degree angles. They can also measure depth, determine flatness and find the centre of circular objects.
Perfect for: Precision woodworking, metalworking and any tasks requiring accurate depth measurements and angle marking.
Tips for using a combination square:
- Adjust the ruler to use it as a depth gauge or measure the parts' height
- Use the built-in bubble level to ensure surfaces are level or plumb
- Interchangeable heads allow for various measurements and use in different applications.
Rafter square
What: A rafter square is a triangular-shaped tool and also known as a speed square or triangle square. It combines several functions into one tool: a try square, mitre square, protractor, line scribe and saw guide.
Why: Rafter squares are primarily used for marking 90-degree and 45-degree angles. You can also use them to find complex angles, rafter angles and often come with common measurement guides.
Perfect for: Quickly marking common angles in carpentry and framing, measuring and marking angles for roofing, stair layout and other construction tasks.
Tips for using a rafter square:
- A rafter square often has "scribe" guides that allow you to accurately mark parallel lines quickly and efficiently. Simply place your pencil in the scribe guide at your chosen measurement and run the square along the edge of the material.
- Using the pivot point of a rafter square alongside a plumb bob creates a makeshift level
- You can use a rafter square as a saw guide for straight cuts.
Callipers
What: Callipers are precision tools to measure the dimensions of objects with high accuracy. They come in various types, including digital, dial and vernier.
Why: Callipers can measure precise internal and external diameters, depths and steps, making them essential for tasks requiring precise measurements.
Perfect for: Metalworking, woodworking, mechanical engineering, 3D printing and applications that require exact measurements.
Tips for using callipers:
- Zero the calliper before taking measurements to ensure accuracy
- Use digital callipers for easier reading and recording of measurements
- Regularly clean and calibrate the calliper to maintain its precision.
Laser distance measurer
What: Laser distance measurers use laser technology to measure distances accurately over long ranges.
Why: Laser measurers provide quick, accurate measurements and are especially useful for large areas and hard-to-reach spaces.
Perfect for: Surveying, construction, interior design and any application requiring precise distance measurements over long ranges.
Tips for using a laser measurer:
- Use a stable surface or tripod to minimise movement during measurement
- Familiarise yourself with the device's functions, such as area and volume calculations and memory functions
- Keep the lens clean for accurate readings and store the device in a protective case.
Measuring wheel
What: Measuring wheels are also known as surveyor's wheels and used to measure distance by rolling the wheel along the ground.
Why: Wheels are ideal for measuring long distances over uneven terrain quickly and efficiently.
Perfect for: Landscaping, road construction, surveying and any task involving measuring long distances outdoors.
Tips for using a measuring wheel:
- Use the wheel on a smooth, consistent surface for the most accurate readings
- Reset the counter before each use to avoid measurement errors
- Choose a measuring wheel with a comfortable handle and a durable wheel for extended use.
