Suggested Standard Quilt Sizes for Beds

Our suggested quilt size dimensions are based in most cases on a mattress depth of 15″. No extra length is included for a pillow tuck. Quilting, if moderate to heavy, may reduce the finished size of your quilt by 1″ to 3″ or more and should be considered when planning the finished size of your quilt.

For example: Mattress width of 60″, length of 80″, depth of 12″

  1. 60″ + (2 x 12″) = 84″ (ideal quilt width)
  2. 80″ + 12″ = 92″ (ideal quilt length)
  3. Quilt pattern should ideally finish at 84″ x 92″ for this bed.

Add more for pillow tuck (add 10″ to ideal quilt length), heavy quilting, longer desired drops, etc.
