What are the measures for a charmpack?(I mean such a square)

5 inch squares

Most of the charm packs, esp. Moda, will have 42 five inch squares in them. Some other major brands will have less than 42, even a few of Moda's have less.

It seems like 5x5 inch squares is the norm for what is called a charm pack now.

I've seen squares available in various sizes - 1.5, 2, 2.5, 4, 4.5, 5, 5.5, 6, 6.5 inches.

It has puzzled me that the jelly rolls are 2.5 inches wide and the charm squares are 5 inches wide.

When the squares are 5 inches wide, it takes two strips 2.75 inches wide sewn together (1/4 inch seam) to equal 5 inches.

Two strips 2.5 inches wide sewn together (1/4 inch seam) end up being only 4.5 inches wide.

I used a charm pack and then 2.5" strips to make a quilt, go to pictures and look for Botany quilt. I used a different material for the 2.5" block. Was very quick and easy but effective.
would post the picture here but haven't figured that out...

Pretty quilt. The proportions are pleasing.

Kate, that quilt is really pretty!

Why would you want them to have that particular relationship, of sewing two together to get the other? I love them at 2.5 inches wide.

If you want to combine 4-patches and charm square, the squares will have to be cut down to 4 1/2 inches. Kind of a pain.
Also, I have noticed that strips that are supposed to be 2 1/2 inches are not always cut true to that measurement. So if you need 1 1/4 inch strips, you might be in trouble there.

I wish the strips were sold as 3 inches wide so they could be cut down accurately.

Thank you,Sherrie.

Also, some blocks call for two rectangles that equal the square unit.
