A hexagon quilt calculator assist quilters in determining the number of hexagons needed for a quilt project where Number of hexagons = (Quilt width x Quilt length) / (Hexagon area x 0.866).
For calculating various dimensions related to hexagonal quilt patterns, this calculator simplifies the process of planning and executing hexagon quilts by providing accurate measurements and quantities.
For example, a Hexagon Quilt Calculator can help you:
- Determine the number of hexagons needed for a specific quilt size
- Calculate the finished size of a quilt based on hexagon dimensions
- Convert between different units of measurement (inches, centimeters, etc.)
- Estimate fabric requirements for your project

Hexagon Quilt Formula
The formula for calculating the number of hexagons needed for a quilt is:
Number of hexagons = (Quilt width x Quilt length) / (Hexagon area x 0.866)
Where:
- Quilt width and length are in inches or centimeters
- Hexagon area is calculated as (3√3 x side length²) / 2
- 0.866 is a constant that accounts for the spacing between hexagons
Example: For a quilt measuring 60 inches x 80 inches using 2-inch hexagons:
- Calculate hexagon area: (3√3 x 1²) / 2 = 2.598 sq inches
- Apply the formula: (60 x 80) / (2.598 x 0.866) ≈ 2,132 hexagons
The Hexagon Quilt Formula is the mathematical basis for calculating various aspects of hexagon quilts.
The formula takes into account the unique properties of hexagons and their arrangement in a quilt pattern.
How to Measure Hexagons for Quilting?
Measuring hexagons accurately is crucial for creating a well-fitted quilt. Here are the key measurements to consider:
- Side length: Measure from one point of the hexagon to the adjacent point.
- Width: Measure the distance between two parallel sides.
- Height: Measure from the top point to the bottom point.
To measure a hexagon:
- Use a clear ruler or template for precision.
- Align the ruler with the flat sides of the hexagon.
- Measure from point to point for side length.
- Measure between parallel sides for width.
- Measure from top to bottom points for height.
Remember that the finished size of a hexagon in a quilt will be slightly smaller than its cut size due to seam allowances.
How Many Hexagons Do You Need for a Blanket?
The number of hexagons needed for a blanket depends on several factors:
- Desired blanket size
- Size of individual hexagons
- Layout pattern
Using the Hexagon Quilt Formula mentioned earlier, you can calculate an estimate. For example:
- For a throw blanket (50″ x 60″) using 2-inch hexagons:
(50 x 60) / (2.598 x 0.866) ≈ 1,332 hexagons - For a twin-size blanket (68″ x 88″) using 1-inch hexagons:
(68 x 88) / (0.649 x 0.866) ≈ 9,056 hexagons
Always make a few extra hexagons to account for any mistakes or adjustments needed during assembly.
What is the Formula for Finding the Sides of a Hexagon?
To find the side length of a hexagon when you know its width or height:
- From width: Side length = Width / 2
- From height: Side length = Height / (√3)
Conversely, if you know the side length and want to find the width or height:
- Width: Width = Side length x 2
- Height: Height = Side length x √3
These relationships are useful when planning your quilt and cutting fabric pieces.
How to Work Out Hexagon Dimensions?
To work out hexagon dimensions, follow these steps:
- Decide on your desired finished size for the hexagons.
- Add seam allowances to determine the cut size.
- Calculate other dimensions using the formulas:
- Width = Side length x 2
- Height = Side length x √3
- Area = (3√3 x side length²) / 2
Example: For a 2-inch finished hexagon with a 1/4-inch seam allowance:
- Finished size: 2 inches
- Cut size: 2.5 inches (2 inches + 0.5 inches for seam allowances)
- Width: 2.5 x 2 = 5 inches
- Height: 2.5 x √3 ≈ 4.33 inches
- Area: (3√3 x 2.5²) / 2 ≈ 8.12 square inches
2 Inch Hexagon Quilt
A 2-inch hexagon quilt refers to a quilt made with hexagons that measure 2 inches on each side. These medium-sized hexagons are popular for their balance between visual impact and manageable piece count.
Key points for a 2-inch hexagon quilt:
- Finished size: 2 inches per side
- Cut size: 2.5 inches per side (including 1/4-inch seam allowance)
- Width: 4 inches
- Height: 3.46 inches (2 x √3)
A queen-size quilt (90″ x 95″) would require approximately:
(90 x 95) / (2.598 x 0.866) ≈ 3,797 hexagons
This size is versatile for various projects, from small wall hangings to large bed quilts.
1 Inch Hexagon Quilt
A 1-inch hexagon quilt uses smaller hexagons, creating a more intricate and detailed pattern. These quilts are often associated with the English Paper Piecing technique.
Key points for a 1-inch hexagon quilt:
- Finished size: 1 inch per side
- Cut size: 1.5 inches per side (including 1/4-inch seam allowance)
- Width: 2 inches
- Height: 1.73 inches (1 x √3)
A lap quilt (50″ x 60″) would require approximately:
(50 x 60) / (0.649 x 0.866) ≈ 5,328 hexagons
These smaller hexagons allow for more intricate designs but require more time and patience to assemble.
How Many 10×10 Squares to Make a Queen Size Quilt
A queen-size quilt typically measures around 90″ x 95″.
To determine the number of 10×10 squares needed:
- Calculate the total area: 90 x 95 = 8,550 square inches
- Calculate the area of each square: 10 x 10 = 100 square inches
- Divide total area by square area: 8,550 / 100 = 85.5
You would need approximately 86 squares of 10×10 inches to cover a queen-size quilt. However, this doesn’t account for seam allowances or specific design layouts. In practice, you might need more squares to accommodate these factors and create your desired pattern.
