Here is an example: box extent 10 x 10 x 14

Add 2" to the preliminary two dimensions (10 positive 2) x 10 nonnegative 2 x 14), and 1/2 of the second digit (10 bisulcate by 2 = 5) added to the closing size (5 plus14 = 19). Add 10" (10 positive 9 = 29) for flexure concluded or tie off the bag. The bag magnitude required for this box bulkiness to bound off the bag is 12" x 12" x 29".

Another way is to use a elastic activity tape and determine all in a circle the box, split that number in partially and add two inches... this is your size. (10 10 10 10= 40 bifid by 2 = 20 nonnegative 4"=24). For the length, activity half way decussate the strait players of the box inferior (5"). Plus the loftiness of the box (5 plus 14") for the smallest physical property. Add more things (10") for crimp finished and or tie off. Using this technique the bag activity is 24 x 29. Now since you cognize the complete dimension needed, you can splinter it lint more to a gusset bag.

Either way you digit it, you will be sheltered mistreatment the formulas above to supply your punter near a bag fitting for their box!

Round Container
1) To find circumference of the bag, work out the the length of the bathtub by 3.14. Divide that full by 2 to get the face down breadth you inevitability for your bag. (Add l in for a looser fit.)
2) Add 1/2 of the diameter to the stage of the paper bag. Add 5 inches to this whole for projection. This is the unqualified physical property of the bag needful.
3 )If fastening bag, add 1/2 the length to the bag dimension in # 2
