Size Chart

[Underwood]

Hi Everyone,

In an effort to find the proper size for my first weight, I found myself constantly going back and forth with the diameter equation to find the proper measurement. I realized that I could easily plug this data into a spreadsheet and have it create the calculations. By doing this, I inadvertently created a size chart. I thought I would share this with all of you as I'm sure it could be helpful. I was unable to attach the link as a PDF to this post, so I have to share it using Dropbox.

Enjoy!

I think this link is non-functioning.

yeah, link not working..

I have updated the link in the post. Let me know if it works!

works. thank you!

from what I have factored based off this guide chart that I found:

Calculate the Inside Diameter:

1. Determine the average. Add up all 5 measurements together, and then divide this answer by 5. This is variable A. PLEASE remember if you measure in inches, you need to convert to millimeters at some point. This conversion might as well happen right now. This conversion calculator will convert the inches measurement to millimeters.

2. Calculate your comfort size range: From now on we are using millimeters. The size range concept is easier to grasp and is a revision of the previous usage of tightness multipliers. Now, everyone will calculate in one standardized way and calculate a comfort size range from tightest to loosest. Knowing your size range should eliminate quite a bit of confusion when it comes to selecting pre-sized split collar weights. Now, simply select the split collar size that is closest to your size judging from your personal tightness preference based on your range.

Multiply Variable A by 0.74. This is Variable B

Multiply Variable A by 0.80. This is Variable C

What we have just done is create a size range using the following chart. We only need to know the smallest and loosest sizes and the intermediate sizes need not be calculated.
Percent Smaller Multiplier
20% (loosest) 0.80
21% (looser) 0.79
22% (loose) 0.78
23% (tight) 0.77
24% (tighter) 0.76
25% (tightest) 0.75
26% (tightest recommended) 0.74

3. Calculate inside diameters for the comfort range: (Formula is D=C/3.14) Divide Variable B by 3.14, this is Variable D. Divide Variable C by 3.14, this is Variable E.

4. Final Results for Sizes with the Comfort Range Defined: The best chance of a fantastic stretching experience will occur with a weight size at or anywhere between these two poles.
<<<------------------------------------------------------------------------------------------------>>>
Variable D
Variable E
Tightest Recommended
Loosest Recommended





AN EXAMPLE OF THE CALCULATION PROCESS FOLLOWS:

Variable A average measurement is 6.0 inches.

Convert 6.0 inches to millimeters: 152.4 mm (Google "inches convert mm")

Calculations:

Comfort Range:
152.4 x 0.74 = 112.8mm = Variable B
152.4 x 0.80 = 121.9mm = Variable C

Find inside diameters:
112.8/3.14 = 35.9mm = Variable D
121.9mm/3.14 = 38.8mm = Variable E

Final Results for Sizes with the Range Defined:
35.9mm <------------------------------------------------------------------------->38.8mm
Tightest Recommended
Loosest Recommended


the range that I fall into is: 55.38mm - 59.88

based off this chart with the inches to mm, I would be: 51mm -55mm with a 8.5" measure..

not sure if I should go for a 55mm inner or a 57.5 inner....cause its most likely gonna have to be a custom order, I want it to be a good pound at least in weight..I want to feel it with all the extra flesh that I have but I also want to be comfortable and not have one slip out or anything painful like that, I have already had WAY TOO TIGHT at like 1/2 that measurement size and been pinched and cut and snipped slightly and bled a bit..so i REALLY want to make sure of the size to get.....

This saved me a ton of time

This chart accommodates both millimeter measurements and inches.

Using the chart on 4 occasions I ended up with measurements between 32mm and 38mm so I went for the smallest inside measurement I could find without custom ordering (34mm) which worked out to be just about right, perhaps 35mm would have been better but this is working out just fine.

This is super helpful! Thanks!
