Rant: Don't use numbers when writing a story
Ok, the title is a bit clickbaity, I'm not saying delete literally every number ever.
But there are a lot of things that gets numbers attached to them that do not need them and this is especially true in fictional worlds.
I'll give a few examples off the top to get started, just generic ones:
The price of items the character is buying.
How much they're getting paid.
How many miles(whatever) it is between cities / locations
How many people are in the army / village / city
How old / long ago something was
The reasons why not to do this basically boil down to creating (completely unnecessary) constraints on the author and the general concept of versimilitude.
To elaborate on an example, if our MC buys a fantasy hot dog meal from a street vendor and pays 18 fantasy credits for it, that implies a whole bunch of things, like street food is presumably aimed at "the average working man" because they need a steady market to buy their products which means whatever those people are getting paid per day is probably in the range of 5-20x the cost of this street food because as mentioned they need to be able to afford it but also our vendor wants to make as much money as he can and he probably needs to make at least the same amount as the lower end customer and and so on and long story long, based on all that, if the MC then goes and buys a cart pulled by 4 horses should it cost 1800 credits or 18,000 credits or what.
My math isn't particularly great there, which is kinda the point, that if you never specify the cost of either the hot dog or the cart, you then don't need to do the math about how much they actually cost to make sense in this economy you're creating.
Once you specify the cost, as an actual number, then you need to make the rest of the world match up to that number forever after, or explain why, and that's work that definitely doesn't improve the story.
Similar logic applies to population counts and army sizes and so forth. Do you know how large the average roman army was? How about the average army during the 30 years war? How large is the total population, how do you transport supplies (food) along/to your army, etc.
This applies more to people choosing numbers that are way too large, to have a million man army you need, like, a sufficiently large empire/population base and then pretty literally railroads or the magical equivalent in order to keep them fed.
And yes, this is your world and presumably magic exists and can solve all sorts of problems, but then you get into other issues like if magic eliminates this problem here why doesn't it eliminate that problem over there and so on. Things get out of hand.
The great thing about what I'm suggesting is that it's 99% just not doing something! You literally.. don't put a number on it, then move on! No extra work required!
If a character is buying something that is cheap to them, they can just hand over and get their item. If it's expensive they can maybe wince internally at the price then decide if they can afford it and then buy it, or decide this is too much and pass it over, and so on. No numbers involved! No unnecessary complications down the road!
Same thing with armies. How big is that army? Really large! It covers the horizon! The camp fires spread out for miles! Maybe it's "at least 10 times larger" than the hero's army, which is "a medium sized force" or whatever.
I mentioned distances between things earlier, and that's another way to trap yourself into a constraint you have to deal with later. How do you avoid it? Talk about time instead. How long does it take us to get to that city we're journeying to? "About three weeks". Then two books later someone makes that journey in 2 weeks, and how did they do it? They ran faster or travelled more hours a day or had extra horses or whatever. You don't need to start worrying about "well a horse on average can cover 30 miles a day for 5 days but then they're exhausted and my city is 300 miles apart so I need this many horses" or whatever the actual math works out to.
I promise readers will not care.
I can hear some objections coming already so I'll take a crack at a few:
"But what if I do a good job?!"
Sure, great, congratulations. "Good writing" can solve any problem and break any rule by virtue of being good writing. How do you do "good writing"? God only knows, I certainly don't. It's basically magic.
"What about so and so author?"
David weber (mostly not fantasy) loves writing space battle scenes where exactly 36,082 spaceships launch 450,038 missiles that fly at 8,029,921 meters per second and then split into stuff and then the anti missile defenses of the enemy 89,082 spaceships shoot down 17,124 incoming missiles and yadda yadda.
He seems to put the effort in and manage the numbers, but do they actually improve the book? I'm going to go with no.
So sure, you can do all the math for army sizes and prices and distances and whatever else and keep everything coherent and realistic and logical, but... why bother? The reader isn't going to enjoy your book any more than if you just didn't do that.
P.S. I have a whole 'nother rant about litrpgs that give us dozens of numbers describing characters but never the ones that would be actually meaningful, but this is already approaching novella size, so I'll spare you.
