Find the perfect size bag for your round object (candle, cup, jar, etc..)


To find the perfect FLAT bag size for your round object, follow the below steps:
  1. Measure the diameter of your object.
  2. Calculate the circumference by multiplying your object diameter by 3.14
  3. The width of your flat bag = ( 1/2 of your circumference ) + .5" minimum
  4. The height of your flat bag = Height of your object + (1.10 * diameter)

For example:Candle diameter = 4", height = 5"
  1. 3.14 x 4 = 12.56 = circumference
  2. Width of bag = (12.56" / 2) = 6.28" + .5 " = 6.78" minimum width
  3. Height of bag = ( 5" + (1.10 * 4)= 4.40 = 9.40" minimum height.
  4. Find a bag size written a minimum of 6.78" x 9.40" (rounding up helps) 7"w x 10 "h

To find the perfect SQUARE bag size for your round object, follow the below steps:
  1. Measure the diameter of your object.
  2. Calculate the circumference by multiplying your object diameter by 3.14
  3. Your circumference is equal to or less than (bag width x 2) + (bag depth x 2).
  4. Your bag height is equal to or greater than the object height.
For example:
  1. Candle diameter = 4", height = 5"
  2. 3.14 x 4 = 12.56"
  3. Our CS3 bag size is 4" x 2.75" x 10.75"
  4. To figure out if this bag will fit our object = ((2x4)= 8 + (2.75 x 2) = 5.5) = 13.5". Our object will fit width & depth wise because 12.56" (our circumference) is less than 13.5". Bag height is also greater than 5" & will allow for a nice tie & fan ( or open) at the top.
