Trying to decide which size drawstring bag you need? A size larger than what “just fits” is the short answer. The larger size is necessary for the bag to close properly and so it doesn't look like you skimped. In order for the bag to draw shut nicely it needs the extra space.
For instance, although you may feel a standard CD jewel case (5” x 5-1/2”) should fit in a 5” x 7” drawstring bag you maybe disappointed in the appearance when you place the item in the bag as the bag will not close tightly and the corners of the case seem to protrude. But… if you place the same CD jewel case in a 6” x 10” bag it will look lovely, the bag will close very nicely and it has the correct appearance. The soft organza fabric needs to be able to fold around the rigid square jewel case for the drawstring closure near the top of the bag to be able to pull tightly shut.
Usable dimensions for a drawstring bag are always less than the actual dimensions. The usable dimension is the inside area of the drawstring bag that can be used for product(s) and still leave room for the bag to draw closed properly. Below are a few examples of actual bag size with their usable dimension size along with a product guide to give you an idea of how the bag will hold popular favor and gift contents.

Fun Tip: What do you do with organza bags when they have served their gift giving life...they go out to the garden, of course. When capturing seeds to sow for next year slip the organza bag over the head of the flower just before it will drop its seeds draw the string around the stem and let the bag do the collecting for you.
