Understanding the Measurements
Rather than the generic, unstandardized, or 'best guess' descriptions and speed values used by most cornhole bag companies to describe their bags, Six By Six provides six standardized data points for each bag measured.
The first four metrics are common physical characteristics: weight, width, thickness, and flop. The last two, faster side force value and slower side force value, are measured using Six By Six's proprietary measurement technique.
1. Weight (measured in ounces)
2. Width (average of the horizontal and vertical measurements)
3. Thickness (thickness of the bag in inches)
5. Faster side force value
6. Slower side force value
The faster side force value and slower side force values are represented by a value that shows the amount of force a fabric requires to move across a surface.
The closer the value is to 1, the less force it takes to move a bag (in general this correlates to a faster).
The higher the value and closer to 10, the more force it needs (in general this correlates to a slower).
Each cornhole bag listed on this site was measured multiple times to create an average value for each metric and the numeric value for the force measurements.
More about Force Value
The generic faster or slower side force values shown in the bag charts are the average of the combined stationary and sliding force values. This generic value represents a general way to describe how the bag will move across a surface.
To calculate the force values, we measure the static and kinetic coefficient of friction of each fabric. We pull the bag and measure the force required to move it across a flat cornhole board surface.
- The closer the value is to 1, the less force it takes (in general this correlates to faster).
- The higher the value and closer to 10, the more force it needs (in general this correlates to slower).
The sliding force value represents the rate a bag will slow down as it moves across a board.
The stationary force value is meant to show how hard a bag will be to "move" if it is sitting on a board.
So, how does this translate to the boards?
If you are wanting to find a 'blocker' bag, you will want a higher stationary force value because it will be harder to push out of the way. Alternatively, if you are looking for a bag to slide up the board, you will look for something with a lower sliding force value.
Force Value vs. Perceived Speed
When most manufactures or players talk about a bag's speed, they are providing a speed value based on their perception of the bag's speed, not based on a standardized, scientific measurement like force value.
The problem with perceived speed data is that the perception of a bag's speed can differ greatly from player to player based on:
a player's throw style (hard throw vs. soft throw, high angle of release vs. low angle of release. For example, Game Changers might be perceived to be a super fast bag to a thrower with a low angle hard throw, but another player with a light throw and high angle might think Game Changers are just right or a middle of the road speed.)
board conditions (high humidity environment vs. low humidity environment; players who consistently play in environments with high humidity might assess the speed of a bag to be much slower than their counterpart using the same bag in a typically low humidity environment.)
scope of reference (if a player has only played with 30 bags, their frame of reference for fast and slow is only as diverse as the number of bags they have played with, but maybe the fastest bag they have played with is actually only middle of the road compared to the fastest bags available on the market.)
Due to the variability in perceived speed values, Six By Six offers force value as a scientific, standardized measurement to assess and compare bags.
More about Weight
The weight measurement is recorded using a scientific scale with a 0.001 ounce resolution and calibrated with Class F certified weights. The weight values presented on this size are in ounces.
More about Flop
This term can also be called its flexibility, slink, slump, looseness, fullness, or fill shift. The flop values are meant to explain how the fabric bends or stretches, and how the fill slide past one another, shifts, or flow as the bag hits and moves on the board.
The values are in a range from 0 to 10. Bags with lower values are looser, where bags with higher values can be described as stiffer or fuller. This value is calculated from the original thickness and another measurement designed to measure how much the fabric and fill can stretch and move.
More about Width
All width measurements are made using an image processing program and with the seam horizontal and at the top. All width measurements are in inches. The horizontal width is from left to right, and the vertical width is from top to bottom. Each measurement is calibrated using digital calipers set to 1 inch with a 0.001 inch resolution.
More about Thickness
The thickness measurement is taken with the bag laying flat on a level platform. The value is determined by measuring the distance between the top surface of the bag and the surface of the platform using a digital depth gauge with a 0.001 inch resolution. All thickness measurements are in inches.
More about Fabric/Seams
In addition, we provide close-up photos of each bag's slick and stick fabrics, seam closure, corner, and thickness alongside the manufacturer's fabric description. See each bag's individual data page for this information.
To make sure cornhole bags are produced similarly, many of the features of the bag have been standardized. Below are the universal standards.
Cornhole Bag Standards
Weight: 15-16 oz (-0.5 oz, + 0.25 oz)
Width: 6 by 6 inches (+/- 0.25 in)
Thickness: 1.25 inches (-0.125 in, + 0.25 in)
Cornhole Bag Standards
Rounded Corners: the corner of a bag can be no more than 0.5 inches (radius of 1.2 inches) from the corner of a square.
