Pace Count Calculator
Tell it how many paces you walk in 100 metres and how far you need to go, and it gives you the number to count on the ground you are actually crossing. It also plans which beads to slide and when, and works backwards if you have already been counting. Nothing uploaded.
Bead plan for this leg
Tick these off as you go
Each number is the running pace total at a bead slide. The dark ones are where an upper bead comes down and the lower group resets.

Two things both called a pace, and they differ by a factor of two
This is the trap that ruins more pace counts than bad terrain does. The word means one thing in the field manual and a different thing on the cord around your shoulder strap.
FM 3-25.26 defines a pace as one natural step of about 30 inches. On that definition 100 metres is 3,937 inches divided by 30, or about 131 paces.
Ranger beads and orienteering pace scales assume the other convention. The Bay Area Orienteering Club's pace counting guide by Evan Custer has you count one pace each time your left foot lands, which halves the number to roughly 65 for the same walking.
Neither is wrong. What is wrong is calibrating in one and then reading a chart written in the other, which puts you at 200 m when you thought you were at 100 m. The counting style selector at the top exists so the tool can show you both numbers side by side and you can see which one your kit expects.
Where the 65 comes from, and why yours will be different
The default here is 65 paces per 100 m counting every other step. That is not a standard, it is a placeholder sitting in the middle of the observed range.
The Gray Bearded Green Beret's write-up on pace count and ranger beads puts most adults between 62 and 75 paces per 100 m in field conditions, with taller navigators at the low end. Custer's orienteering guide suggests starting from 55 and adjusting, which is a shorter count and a longer stride, consistent with runners rather than loaded walkers.
Run those through the stride arithmetic and the disagreement mostly dissolves. At 65 paces per 100 m each pace covers 1.54 m, so each foot strike covers 0.77 m, which is 30.3 inches. That lands on the field manual's 30 inch step almost exactly.
The 62 to 75 range works out to steps of 31.7 down to 26.3 inches. Custer's 55 is a 35.8 inch step, which is a running gait, not a walking one. So the numbers describe different people moving differently rather than a contradiction.
What the terrain multipliers are, and what they are not
Be clear about the confidence level here, because a lot of pace count content is not. Only one of the eight multipliers has a published range behind it.
The steep uphill figure of 1.25 comes from the Gray Bearded Green Beret page above, which puts the penalty at 10 to 20 extra paces per 100 m on steep ground. From a 65 baseline that is 75 to 85, and 1.25 sits in the middle at 81.
The other seven are reasoned starting points, not measurements. FM 3-25.26 lists slopes, winds, surfaces, elements, clothing and visibility as things that change your pace, and gives directions rather than numbers for any of them.
So treat every multiplier as a first guess to be replaced. Walk a known leg of the ground in question, compare the count you actually took against the count the tool predicted, and put the ratio into the override box in the advanced panel. That number is worth more than anything on this page.
One detail the presets do capture: gentle downhill is the only case where the count drops, because the stride lengthens. Steep or slippery downhill pushes it back up, since braking shortens the stride again.
How the bead plan is worked out
A standard set is nine lower beads and four upper beads on one cord. Each lower bead is 100 m and each upper bead is a kilometre.
The arithmetic that catches people is that an upper bead is worth ten lower intervals, not nine. You slide the ninth lower bead at 900 m, and it is the tenth 100 m that pulls an upper bead down and resets the lower group.
That sets the capacity of the set. Four upper beads at ten intervals each plus nine lower beads is forty-nine intervals, or 4,900 m, which is why a 9-and-4 cord is usually described as good for about 5 km. Ask for a longer leg than that and the tool tells you the cord has run out rather than silently wrapping around.
Worked through with the defaults: a 500 m leg on the flat at 65 paces per 100 m is 325 paces total, five lower bead slides, one every 65 paces, no upper bead. Take the same 500 m up steep ground and the multiplier of 1.25 makes it 81.25 paces per 100 m, so 406 paces and a slide every 81.
Push the leg out to 1,500 m on the flat and it becomes 975 paces, fifteen slides, which is one upper bead plus five lower beads showing on the cord at the end.
Calibrating on whatever you can actually measure
Custer's guidance is to test on short legs under 200 m against features you can identify, across trail, open ground, uphill, downhill and thick vegetation, then rebuild your pace scale if you are consistently off.
Most people do not have a measured 100 m course to hand, so the calibration panel takes any course length in metres or yards and scales it. Walking a 600 m stretch and dividing by six is the method the field manual describes, and it is more reliable than 100 m because a single miscounted pace matters six times less.
The most common self-inflicted error is the football field. Count 60 paces end to end on a 100 yard field and it is tempting to write down 60, but a 100 yard field is 91.44 m, so your real figure is 65.6 paces per 100 m.
Use the 60 and you will walk 300 paces expecting to be 500 m along, having actually covered 457 m. That is 43 m short of where you think you are, which is enough to put you on the wrong side of a stream junction.
Whatever course you use, walk it in the boots and the load you will actually carry. A pace count taken in trainers on a running track will not survive contact with a rucksack.
FAQ
How many paces is 100 meters?
Counting every other step, most adults in the field land between 62 and 75 paces per 100 metres, which is the range the Gray Bearded Green Beret quotes. Counting every foot strike instead, the same walking comes out at roughly 124 to 150. There is no single right answer because the number is a property of your legs and your load, not of the distance, which is why the only figure worth using is one you measured yourself on a course you walked.
Do I count every step or every other step?
Either works as long as you stay in one convention, but the two are not interchangeable and a number quoted in the wrong one is out by a factor of two. FM 3-25.26 defines a pace as one natural step of about 30 inches, so a count in that convention is around 131 per 100 metres. Ranger beads and orienteering pace scales assume you count each time the same foot lands, which halves it to about 65. Pick the one your bead set or your pace card was built around and calibrate in it.
How far will a set of ranger beads count?
A standard set has nine lower beads worth 100 metres each and four upper beads worth a kilometre each. An upper bead covers ten lower intervals rather than nine, because the tenth 100 metres is what pulls it and resets the lower group, so the set reads out to 4 kilometres on the upper beads plus 900 metres on the lower, or 4,900 metres in total. Past that you have run out of cord and need to break the leg at a checkpoint.
