As someone else commented just above, I also no...1. As someone else commented just above, I also noticed using https://hexagoncalculator.apphb.com/ that the side/center-to-vertex lengths and vertex-to-vertex lengths aren't quite the values the blog posts claimed, but actually 3.46 and 6.92 miles. This isn't a particularly bad mistake, but a 5 mile hex has sides/side-to-vertex of 2.9 (so about 3) and vertex-to-vertex length of 5.8 (so about 6) miles when rounded to 1 decimal too, so it's not really that different.<br /><br />2. One could also argue that with the horizon of a flat plane being about 3 miles away for an observer at a height of 6 feet, a 5-mile hex is the better choice for a part being able to see from the edge (last half-mile or so) from the previous hex to the middle of the one they're about to enter. Or from the middle of the one they're in to the first half-mile or so of each neighbouring hex. In a 6-mile hex, in the middle they can *only* see their current hex. I would think that which option is better depends in part on if you want to use single-biome hexes or not, whether rivers and roads neatly follow hex borders (even subhex ones!), etc. And of course the average/maximum height of vegetation (if you're on a grassy plain where the grass is 3 feet high all over, a 6-foot observer is only observing from a height of 3 feet, and their horizon is 2.1 miles away), hills and other topography changes etc. likely matter much more how far something can be seen. In Fantasy RPGs, levitation (if you can control the altitude)/flight spells become very useful for mapping if you take observer height into account.<br /><br />3. Point 3 is basically meaningless, at least for just wanting half-mile subhexes. You could have a 5-mile hex which is 10 subhexes across instead of 6 and 12 and it would achieve the same thing. The rest of the math regarding 1/24 mile sub-subhexes (an arbitrary choice in itself) would work out the same.<br /><br />There's nothing wrong with 6 mile hexes, but it's not *that* superior to a 5-mile one either. Or most other sizes used in various games. I say use whatever works or is supported by the general travel, encounter, and other systems you're using. For example, Harnmaster uses 5-<i>league</i> hexes, and a league was/is customarily defined as about as much as a person walks in an hour, about 2.5 miles or 4 km (so a hex is 12.5 miles or 20 km). The travel system outlines travel in 4-hour intervals, and in that time 5 leagues is possible on roads or trails through flat areas, but not through cropland, forests, hilly terrain, etc. It doesn't use subhexes that I'm aware of, instead just mapping everything naturalistically, and showing a scale in addition to the 5-league hexes.<br /><br />And lastly, especially down at the level of 1/24 miles, things start getting really opaque for those of us more used to km. 1 mile is still "something more than 1.5 km" (1609 meters and change) and half a mile is "less than 1 km" (0.8 and change), but 1/24 needs a calculator. Another reason why I like Harnmaster's travel/distance, since it offers conversion ratios to both metric and US/Imperial, and doesn't strongly favour either (smaller-scale stuff mostly uses feet iirc). 5 miles is 8.05 km and 6 miles 9.66 km, but those 5:8 or 6:10(ish? 9.5? 5 miles may be slightly better here!) ratios are rarely mentioned in most mainstream or even indie RPG stuff due to the US standards dominating.unknown2https://www.blogger.com/profile/17767039287440123174noreply@blogger.comtag:blogger.com,1999:blog-4519238203196996408.post-9568482900521478542020-01-28T12:42:22.033-08:002020-01-28T12:42:22.033-08:00I did the math, and this may not be perfect, heavy...I did the math, and this may not be perfect, heavy approximations and such, but the US is about 121,777 6-mile-hexes squared.Andrew Sawyerhttps://www.blogger.com/profile/15263056911810945780noreply@blogger.comtag:blogger.com,1999:blog-4519238203196996408.post-9338518490843678912018-02-02T16:11:03.487-08:002018-02-02T16:11:03.487-08:00Daniel, that's slightly incorrect.

I'm working on a campaign that should span the party around 3 months of in-game time, and I'm wanting to present it as a hexcrawl. My idea is to create the size/scale of the campaign region based around that. That gives me roughly 90 in-game days to work with. <br /><br />If I want the party to reasonably be able to explore 1 full hex in a day (assuming no adverse conditions, so they're all healthy, not trudging through swamps, etc), it looks to me like the 6 mile hex should be good for that (since a 6 mile hex is just slightly less than 24 square miles) - in fact, if they were in a plains area and could see all around, I would assume the could do it in much less time than a day. Is this reasonable for me to assume?<br /><br />Thanks!brandon karlishttps://www.blogger.com/profile/03965986442476126755noreply@blogger.comtag:blogger.com,1999:blog-4519238203196996408.post-6903918475289952082016-02-04T14:56:12.898-08:002016-02-04T14:56:12.898-08:00If anyone wanted to know ('cause I did!) the a...If anyone wanted to know ('cause I did!) the area of the 6 mile hex. is: 31.82643359m2. <br /><br />A hex is 6 Equilateral Triangles, the base and sides are 3.5, so I figured out the height:<br /><br />3.5xCos30 = 3.031088913<br /><br />Then to find the area of each Triangle:<br /><br />1/2x3.5x3.031088913 = 5.304405598<br /><br />Multiplied that by 6 for the full area of the hexagon:<br /><br />5.304405598x6 = 31.82643359m2 per 6 mile hex.<br /><br />OR if you replace the 3.5 with the actual 3.49 as it should be, the answer becomes: 31.64482806m2<br /><br />And someone please correct this if it's wrong <3Anonymoushttps://www.blogger.com/profile/17260633905350936642noreply@blogger.comtag:blogger.com,1999:blog-4519238203196996408.post-31528278644602141812015-09-11T08:29:33.724-07:002015-09-11T08:29:33.724-07:00How do you break the hex down into more hexes?

I think your recommendations might be a bit short, given the horizon calculations on the wikipedia page.<br /><br />A 1,000-foot prominence (a large hill, half the size of the smallest mountain, by one definition) is visible from 38 miles away, which is roughly 6.5 6-miles hexes.<br /><br />A 9,000-foot prominence (which is roughly the distance that Everest towers above its base camp), is visible from 19 hexes away!<br /><br />Now, all I'm doing to get these numbers is to assume that you can see anything that can see you.<br /><br />Oh, actually, I see I'm doing that wrong. According to WP, the way to tell the distance to tall objects is to add together the observer's to-the-horizon distance with that of a hypothetical, second observer, atop the thing you're trying to see.<br /><br />So if you're on a 1,000-foot prominence trying to see a 9,000 foot prominence, you can see that from 6.5+19=25.5 hexes away.

You are correct, 7^2-6^2 does not = 3.5^2<br /><br />And 6.98^2 - 6^2 does not = 3.49^2<br /><br />That is because these numbers are longer decimals that have been rounded up to the nearest 100th of a mile (or 52.8 ft). What you need to do is start with a 6 mile line and then determine what the lengths of an equalateral triange with a height of 3 is.
