What Are Half-Square Triangles?
Half square triangles (HSTs) are a common quilting block that can be used to create a variety of quilt designs. They consist of two triangles made by cutting a square in half diagonally, resulting in a right triangle. The two triangles can then be sewn together to create a square with a diagonal seam.
The size of the finished HST block depends on the size of the starting square. To make it easy to determine the size of the starting square needed for a particular finished block size, quilters often use a half-square triangle size chart. This chart provides the dimensions of the starting square needed for a range of finished block sizes, taking into account the seam allowance that will be used to sew the triangles together.
By using a half-square triangle size chart, quilters can ensure that their blocks will be the correct size and that the points will line up accurately.
Definition and Uses
Half-square triangles are an essential component of quilting. They are versatile enough to be used in many patterns, making them a staple in the quilting world. Half-square triangles are made by cutting a square into two triangles.
These triangles are then sewn together to create half-square triangles. They can be used in a variety of ways, including as borders or in the body of the quilt itself. Many quilters use half-square triangles to create star patterns, pinwheels, and other geometric shapes.
The options are truly endless when it comes to using half-square triangles in quilt making. So, if you enjoy quilting, mastering the half-square triangle will certainly come in handy.

Therefore, it’s essential to have a half-square triangle size chart at hand, which will help you select the perfect size for your quilting project.
List of Common Sizes and Their Uses
Half-square triangles are a popular quilting element that can be found in countless designs and patterns. Knowing the common sizes that are used can help you create precise and beautiful projects. The standard half-square triangle sizes range from 1 inch to 7 inches, with half-inch increments in between.
The most commonly used half-square triangle size is 2 ½ inches. This size is great for beginners because it is easy to work with and can be used in various patterns. Larger half-square triangles, like 4 ½ inches and 6 ½ inches, are better for more complex designs that require bigger pieces.
On the other hand, smaller half-square triangles, like 1 ½ inches and 2 inches, are perfect for intricate and detailed designs. Remember, these sizes are just suggestions, and you can use any size that you prefer. The right size will ultimately depend on your project’s needs, so don’t be afraid to experiment and find what works best for your design.
How to Calculate Half-Square Triangle Sizes
If you’re new to quilting or just need a refresher, figuring out the size of your half-square triangles can seem daunting. Luckily, using a half-square triangle size chart can make the process much easier. This chart will give you the finished size of the half-square triangle based on the desired size of the block.
For example, if you want a 4-inch finished block, the chart will tell you to cut two 4 7/8 inch squares (or two squares that are 1 3/8 inches bigger than your desired finished size). Then, you will draw a line diagonally from one corner to the other on the back of one of the squares, sew 1/4 inch on each side of that line, and then cut along the line to create two half-square triangles. Using a half-square triangle size chart takes the guesswork out of the equation and helps ensure that your finished quilt blocks are the size you intended.
Step-by-Step Guide with Examples
Calculating half-square triangle sizes can be a daunting task for beginners and even experienced quilters. However, with a few simple steps, you can quickly and easily determine the size of your HST block. Firstly, decide on the size of the finished HST block that you want, and add 7/8 inch to this measurement.
This extra length will allow for seam allowance. Once you have your measurements, cut two squares from your chosen fabrics with this dimension. For example, if you want a 4-inch finished HST, cut two 4 7/8-inch squares.
Next, place the fabric squares right sides together and draw a diagonal line from one corner to the opposite corner. Sew ¼ inch away from the line on either side and then cut along the line. Press the seams open, and you now have two HSTs that are half an inch bigger than your desired size.
Trim the blocks to your desired size using a ruler and cutting mat. And voila! You have successfully and easily calculated your HST sizes.
