Custom BIAB Measurements March 23, 2015 17:59
So, you want to buy a custom made and sized BIAB bag. Well isn’t that lovely! First thing’s first, I will need measurements from you so I can make your “custom sized” bag. Believe it or not, a lot of people forget this step. I put orders on hold until I receive the information I need, and I check all dimensions you provide. Tedious? Yes. But that way I know you’re getting a bag that fits your vessel.
How do you measure your kettle, what measurements do I need from you, and why are they important? Let’s talk about the Premium and Classic styles first.
For these styles, I need, at a minimum, the outer diameter and inner height. The outer diameter MUST include any lip that is around the top edge of the kettle. This is important so that the bag is made large enough to fold over that lip. The inner height is to be measured from the bottom of the kettle, or false bottom, up to the very top where the bag will fold over.
Now for the Premium Style, the same rules as above apply, although I also need the circumference around your vessel about 2-3” down from that top lip, where the webbing and Velcro would fasten. I use pi to generate the circumference for making the body of the bag, so if the circumference you gave me is the same size, or smaller than the one I get using pi on your outer diameter, I will question it. If your kettle has a lip, it should be smaller, since that area of your vessel is smaller….follow me? Being off by a couple inches may not seem like that big of a deal, but the Velcro pieces may not line up properly, rendering them useless. Nobody wants useless Velcro flaps.
Measuring for a cooler bag is pretty simple. I need the inner AND outer length, width, and height. See? I told you it was simple!
