Inches per turn 2025
Reid Carter reply :
If I get a reel that is a 6:3.1 with 25 inches per turn would it be suited for deep diving crankbaits the same as a reel that is 5:3.1 with 25 inches per turn? A lot of people look at more of a 4 or 5 gear ratio for crankbaits but what if a 6 takes up the same amount of line what is the difference?
IAY reply :
They are effectively the same, in terms of bait presentation.

What about in terms of power? Will it wear me down more with a 6:3.1 even if the inches per turn are the same?
Mike L reply :
No. You're turning the handle the same amout of times to reel the same amout of line.

IPT trumps ratio. 25 ipt is more what I'd expect from a 6.x:1. My deep cranking reels are <20 ipt

Will it wear you out..no. will a lower gear ratio with the same ipt have more cranking power..yes

Then the question becomes, when do you need the extra power? Its not like we are throwing 1# musky lures around. For a typical bass fisherman, would it make sense to ever buy a 5:1 over a 6:1 in the same IPT? Whole new can of worms...

One thing I can think of is that for a 6.1:1 reel to have the same I.P.T. of a 5.1:1 reel, is going to require the 6.1:1 reel to have a much smaller diameter arbor on the spool. Having the smaller arbor means it is going to take even more line to fill the spool properly. Most spools already hold too much line in my opinion.

Actually in the case of the original post, the IPT is standard for 6:1 and fast for 5:1 suggesting a very shallow and very large dia spool on the 5:1.
IPT is measured with the reel full of line, correct? So depth of the spool won't make any difference in IPT, its all about the final diameter of the spool (full of line) in which case a tiny spool would have the same IPT as a shallow spool if the final diameter of the spool full of line is the same.

Never suggested that it would change IPT, only that it would take much more line to fill a 6.1 reel that has the same IPT as a 5.1 reel. The arbor will be smaller on the faster reel to reduce the amount of line pick up.
Are we dealing in real world situation or hypotheticals?
J Francho reply :
There's more variables to "cranking power" - or a better term: leverage - than just ratio. Actual gear size, weight, material, tooth size, and geometry each contribute. Want to know the difference between a $100 reel and a $400? Chances are it's in one of things I listed above.

Hypothetical as i assume neither of us has the two reels to test. But obviously in real world fishing aspects.

The reel that has the larger spool will have more line on it at the end of a long cast and the ipt would be closer to the listed rating verse a reel with a shallow spool at the end of a long cast.
Delaware Valley Tackle reply :
The width of the spool has more affect on the difference in retrieve over the length of a cast than the depth of the spool but this would not even be on my radar while out on the water.

If the casts are the same, wouldn't the amount of line being casted off be the same, thus the spool size remain the same after a cast? You'll just have more line on one and less on the other, but the size of the spool should be exactly the same.. thus IPT will be the same.
J Francho reply :
I've been waiting for reel makers to start using wide, shallow spools, combined with high gear ratios to maintain a near constant IPT through out the retrieve. So far, haven't seen anything of the sort. So, you'd have a spool that is maybe 1/3 the diameter m, but twice as wide. Even though it might be a 7.1 reel, it would only pickup 25 IPT. Would be cool for cranking.

Please to show me your perpetual motion machine. The diameter of the spool, is part of the equation, so assuming both were spooled equally. There would be no difference in the cranking power.
Reid Carter reply :
Thanks guys! Gonna go with the 6:3.1 Diawa costal since it takes in the same amount of ipt as the kvd cranking reel at 5:3.1. Plus the blue handle will match the blue pole so it will look sweet!

IPT is based on a full reel spool.
Reel size matters, larger reels have larger diameter and or wider spools. Inches per turn is based on the circumference; 3.14 X diameter. Devide gear ratio into IPT then dived by 3.14 = your full spool diameter. i.e.; 25 IPT with 6.3:1 ratio = 1.26 diameter spool, typical size 100/200 size bait casting reel. Make a 40 yard cast, the remaining line on the spool is smaller diameter, approximately 1.00 diamter. The IPT of 1.00" diameter spool at 6.3:1 = 19.7", the IPT changes as the line comes off or back onto the reel. Larger wider spool holds more line, diameter is reduced less.

It's a good thing Newton is dead, cause this would kill him. Wait, he just rolled over. The diameter of the arbor has no bearing on the IPT. The diameter of the spool does, actually to be perfectly accurate the diameter of the line on the spool does, wether you have 1000 yards, or 1 foot of line spooled, and as someone mentioned above IPT is not consistent, it increases as the diameter of the line on the spool increases as line is retrieved, and this rate of increase is affected by the width of the spool and the diameter of the line. Which is why my frogging reel is an old Pflueger Trion wide. as a long cast can leave me with 1/2 a spool of line. 23rd in math and science indeed...

Here is my thought, if you have two reels, one is a 5.0:1 and the other is a 6.0:1 and the reels both use same exact spool. Lets call the arbor 1" for math sakes. Make 1 turn of the handle and the 5.0:1 reel picked up 5" of line and 6.0:1 reel just picked up 6". For both of these reels to pick up 5 inches of line on the first turn of the handle and to then stay equal with each other throughout the retrieval of line the 6.0:1 reel would need to a have a smaller arbor sized at .833 inches. Since both spools are the same besides the arbor dia. the one with smaller dia. will hold more line.
Newton was a bit of a hack, now Einstein who by the way proved that some of Newton's idea's were incorrect, was a true genious.

Never even notice it, especially if I am catching fish.

When you have two reels of equal IPT the reel with the physically larger gears will have more "cranking power".
WRB reply :
Lots of factors affect cranking power; Archenemies lever for example longer handle = more power. Torque can be reduced by friction; ridged frame with and precision alignment and tolerances of gears, bearings, shafts all affect a reels cranking power.
Hard to beat a good solid round reel for cranking.

Here is MY thought, where is the Advil?
Apply the same logic you used above (using the term loosely) to a spool with line ready to fish, and work backwards, and you,ll see it makes no difference where you end up, in this case the arbor.

Sorry, I won't prove your point for you. You will have to write your thoughts out and share them.
