So you bought a hackle cape or saddle to tie some of your favorite fly patterns. The only problem is, the hackle feathers on capes and saddles will vary in size to some degree.  When tying, you’ll want to ensure that you are using appropriately sized hackle which will ultimately lead to well proportioned flies. Enter hackle gauges. Hackle gauges are tools designed specifically to measure the length of the hackle barbs to ensure you’re using the correct size hackle feather for the hook you’re tying on. Better proportioned flies will not only look better neatly arranged in a fly box, but they’ll be sure to land more fish too. 

How to Use a Hackle Gauge

Using a hackle gauge is incredibly simple. Most hackle gauges come with a hole in them to mount on a vise post, however some are designed to lay flat on a table. Simply select the hackle feather that you would like to measure and wrap it around the post on the hackle gauge causing the fibers on the feather to splay apart. The point where the hackle fibers end is where you should take your measurement. Check out the video below from tightlinevideo for more instructions on measuring hackle.

The oval post hole helps the gauge rest at an angle that’s easy to read.

This high quality gauge has an oval post hole that is designed to fit on most standard ¾” vise posts. The oval hole helps the gauge rest at an angle that’s easy to read and always at the ready. Lastly, the “Nail-Head” post helps prevent the hackle from slipping off of the gauge as you make your measurements. 

Griffin Hackle Gauge

Another, cheaper, option to consider would be the Griffin Hackle Gauge. This wooden gauge mounts to a tying vise post similarly to the offering from Whiting. This gauge only claims to be accurate for hackle sizes down to 16 due to the positioning of the post having a fair amount of tolerance. If you don’t regularly tie small flies, the Griffin Hackle Gauge will get the job done for you.
