How Much Farther Can You Cast With A 10 lb Line vs. 20 lb Line? Results Here
By: Luke Simonds on January 4, 2018
I’ve always been curious to know how much farther a 10 lb line can cast relative to a 20 lb line (all else considered equal).
But until completing this latest casting experiment, I never knew how quickly casting performance declines when bumping up to a higher line…
And the results were shocking!
Casting Experiment Details
For this test, I put the focus on braid line because it is what most of us use when trying to maximize our casting distance when using spinning tackle.
It seems as if many inshore anglers are using braided line in the 10 lb to 20 lb range to target redfish, seatrout, and snook.
So I thought that would be fun to know how much casting distance that those who use 20 lb line are giving up by going for the added power.
Both lines have very small diameters, so my hypothesis for this experiment was that their casting distances would be within 10% of one another.
Based on some feedback from the first test where I analyzed the casting difference between mono vs. braid, I performed one test to resemble a heavy bait and another to resemble a lighter bait.
Here are the core variables that are in this experiment:
- Rod Lenght: Equal – both the exact same 7’6″ TFO rods with the same power rating
- Reels: Equal – both lines were on the same sized Shimano Stradic Ci4 reel
- Lures: Equal – used teardrop shaped weights to minimize the wind resistance variable
- 1st test used 3/16 oz to resemble lighter lures
- 2nd test used 1/2 oz weights to resemble a heavier lure
- Casting Force – As equal as possible without a $$$$ machine
- Line Gap: The gap between the edge of the spool and the outer layer of the line is a big factor with spinning reels, so I made sure to keep them equal.
- Line Sizes: One reel was loaded with 10 lb braid while the other was loaded with 20 lb braid
Note: Both lines were made from PowerPro, and they both were newly spooled.

Given the 20%+ difference in casting distance between these two lines, we all need to consider the casting distance implications when deciding between one size or another line.
I use artificial lures 99%+ of the time which requires a lot of casts, so I always favor the lighter lines because they allow me to cover more water with less effort.
This test revealed that the 10 lb line enabled me to cast ~30-feet further… and although that seems relatively small, that equates to an entire football field of water that I can cover every 10 casts.
That is a whole lot of extra water coverage which will surely turn in to more strikes and fish caught.
So our goal should be to select the lowest line strength that we trust can handle our target species.

P.S. – Please be sure to share this post with any of your friends who use spinning tackle so that they know the importance of selecting the right sized line… this test sure made me think harder about the line sizes I use.
