Drafting dress making patterns to your own custom measurements, or making pattern alterations, and then measuring and marking on fabric and then cutting it all out accurately, all are a breeze if you have the right tools.

The following measuring tools are what you need if you want your sewing life a lot easier, while you conceptualise your own patterns and then materialise them and make beautiful garments.

Just ensure that whatever you buy, they are not made of flimsy material and they are made well without any jagged edges and the markings and printings on them are clear and readable. It is an advantage if the rulers have metric and imperial measurements marked

Measuring tape

Goes without saying that measuring tape is the number one thing you need in sewing. You can do without any other tool in this list when sewing, but not this one. Sometimes it can be enclosed in a case and can be extended and retracted.

Straight rulers /Yardsticks

The measuring tape is a flexible measuring tool but sometimes you need a non-flexible (read rigid) measuring stick for your measuring. For eg., you need to measure straight on fabric.

These rulers can be made of metal or wood or plastic. The one I have are made of wood. It can be 24 inches or 36 inches long.

Ideally you can buy a 18″ x 2″ clear plastic ruler; You also need a small plastic ruler for small measurements. I have a 24 inch plastic ruler. Transparent rulers are great as you can see where you are putting the ruler on.

I have a scale with a small projection in the middle with which you can hold on to it. I really like it. No grappling with the edges to lift it up. I think this is what designers use.

L-shaped ruler (L-scale)

This scale has two sides – it usually measures 24″ x 14″ and is used to mark fabric straight, corners correctly. It can help to keep the grainline of the fabric correct. Keep the scale on the fabric and align against the edges so that the other edge becomes completely straight. Also called Tailor’s Square.

French curve ruler

Sewing guage (Hem guage)

This is a tool you can use to mark your hems and seams accurately. It is an adjustable ruler. You can make this one yourself using a cardboard sheet.

Compass

This is helpful to make small circles. The regular compass can be used to make small circles – useful in marking designs for embroidery. But for large circles you need something bigger.

You can make a compass yourself by attaching string to two pencils. The string should measure slightly more than the circle you want. Tie the two pencils on both edges of your string with the circle’s radius as strings length. Hold one pencil at the center of the circle you want to draw and using the other pencil draw your circle..

Protractor

You can use this to mark angles. This is especially useful when you are cutting fabric pieces for patchwork when you will need to match edges and angles accurately, especially if you do not own the quilter’s scale.

Cutting mat

This is an excellent measuring surface – the primary purpose of the mat is to protect your work surface as you cut with your rotary cutter. But the other purpose is wonderful too – measuring and marking with accuracy. The mat has all the markings on a ruler on a larger scale with 1/2 inch grid markings and inch and metric measurements.You can buy it as big as 36″ x 48″

I have all the above tools, but you can do better and buy even more. You know the adage – measure twice and ….. Other measuring tools you can use are Grading ruler or Grid ruler, flexible ruler, design curve ruler, Triangle ruler, and Bias ruler. The best type of tools will give you great accuracy in your sewing projects. And more the better.

What is L-square ruler used for?

The L square ruler is used to get perpendicular lines against a straight line. You can use this to check that you are cutting your fabric correctly and ensures alignment of fabric along the grain. The L-square ruler has 2 arms on either side meeting at a 90 degree angle. One side of the L square ruler is kept along the edge of the fabric or pattern piece (flush against the edge) – this will ensure that you will get a perpendicular line against the other edge of the ruler.

Difference between a flexible ruler and a measuring tape

Flexible rulers are usually shorter in length compared to measuring tapes. The flexible ruler is used to mark curved lines or irregular shapes. Measuring tape is usually used to mark straight lines.
