Basket Dimensions Given Fabric Size

The Basket Dimensions Given Fabric Dimensions calculator computes the finished dimensions for a fabric basket give the length, width, and corner cutout for a piece of fabric.

INSTRUCTIONS: Choose units and enter the following:

• (a) = length of fabric 
• (b) = width of fabric
• (c) = size of square cutout 
• (sa) = seam allowance

Note: the width of your basket will be twice the size of your square cut out.

Basket Dimensions Given Fabric Dimensions (): The results are returns in units of inches.  However, these can be automatically converted to compatible units via the pull-down menu.

Basket Making Directions with Loose Lining:

• Supplies
  • 2 pieces of outer fabric cut to size a, b, and c
  • 2 pieces of lining fabric cut to size a, b, and c
  • 2 pieces of interfacing cut to size a, b, and c
  • 2 pieces for handle
• Instructions
  1. Cut fabric, lining and interfacing based on dimensions a, b, and c
  2. Cut fabric for handle
  3. Attach interfacing to wrong side of outer fabric and handle
  4. with right sides together, sew outer fabric pieces together along the bottom (where cutouts are)
  5. press seam open and topstitch
  6. with right sides together, stitch outer fabric pieces together along side seams
  7. press seam open and topstitch
  8. box bottom (match bottom seam to side seam and stitch the diagonal)
  9. flip right side out
  10. attach handles to sides - equal distance from side seam - with 1/4" seam allowance
  11. REPEAT steps 4-8 for lining
  12. place outside fabric INTO lining (right sides together)
  13. sticth top leaving a gap to flip 
  14. flip and topstich top edge 

The Math / Science

The Basket Dimensions Given Fabric Dimensions equation computes the dimensions of a finished basket given the length, width, and size of square cutout.
length = a - 2c - 2sa

width = 2c

height = b - c - 2sa
