Measurements and Dimensions

Hi Folks,

This post first was published in a slightly different version on October 10, 2016 over on the Daily Journal. I’m reposting it here because I felt it needed a broader audience and might help some of you.

Got a great email from a respected writer friend recently (Thanks, JGV!) regarding my current WIP (back in October, 2015). He wrote

What about doing away with the specific dimensions and leaving the images of the structures, etc., up to the reader’s imagination unless it’s critical to the story. Maybe imply those measurements through dialogue or description like “cramped” or “spacious.” (The account of Noah’s ark might’ve worked better without enumerating cubits.)

That’s a good and valid and point, and as it turns out, he caught me just in time. He made me think.

So when should we include dimensions and when should we not include them? As my friend mentioned, they should be included when they’re critical to the story.

That sounds simple, but beneath the surface it’s problematic. To at least some degree, the reader determines what is critical and what is not. Omit the dimensions and some readers will find the writing “thin.” Include them, and other readers will skip over that part, as I have done occasionally in Heinlein and Asimov novels.

So to expand a bit on the discussion of what should be included, maybe dimensional details should also be included when they’re not critical but still interesting and/or entertaining.

Which leads us to wonder how to determine what is or is not interesting and/or entertaining. To the reader. (Always remember there’s a reader on the other end of the writing.)

As I wrote earlier, my friend’s email made me think. What I came up with is this question and the following rules of thumb:

Q: What exists within the character’s and reader’s probable shared area of experience?

1. If the feature you want to describe does NOT exist within the character’s and reader’s probable shared area of experience (e.g., a lunar colony), include the dimensions.

2. If the feature DOES exist within the character’s and reader’s probable shared area of experience (e.g., a bedroom within the lunar colony), do NOT include the dimensions. Here you would opt instead for descriptors like “cramped” or “spacious” because the reader has seen an apartment and can relate.

I like to think I already knew this, but if I did, I hadn’t yet realized that I knew it. I do now, so it’s more firmly rooted in my subconscious. That’s a Good Thing.

As one other more or less minor consideration, I’m writing into the dark here. I’m allowing the characters to tell the story. (A technique I highly recommend because it’s so freeing.)

So say a character wants (or needs) to know specific dimensions as evidenced by her awe at first stepping into a lunar colony. Should I stop the Receiving Liaison who appears at her shoulder (having noticed her sense of awe) from delivering a short canned speech regarding the massive dimensions?


The colony is new and wonderful to the character. It’s also new and (I hope) wonderful to most readers. So the dimensions are necessary, though probably not critical.

But should I also then drill down to the nitty-gritty and describe in meters and feet the size of the bedroom in the apartment the character is eventually assigned?

Again, no.

The apartment (living room, bedroom, kitchen, bathroom) already exists within the character’s and reader’s shared experience.

So in that case, the character might note (for example) there’s barely room for a double bed in the bedroom, much less the seating area and walk-in closet the character enjoyed in her home on Earth. But she doesn’t need specific dimensions for that.

And much as people generally disagree with differences between genders in this bizarre day and age, whether or not a character will wonder about dimensional details (and so whether the writer should include them) also goes to the character’s gender.

A character who has spent his life excavating sites like the Queen Open-Pit Copper Mine in Bisbee Arizona probably won’t wonder at the specific current size of the lunar cavern in which he works. If he does so at all, he probably will do so via comparison (e.g., “cramped” or “spacious” as compared with Queen Mine or some other place he’s been).

But if his wife is allowed to visit the worksite, she might well ask questions like, “Wow! How big is this place?” And when he answers, he might well brag. “Well, it’s only (insert massive dimensions) but it’ll be (insert even larger dimensions) when we’re through.”

As an added thought, this morning I got another email from another very good writer friend whom I respect a great deal. He recommended writing using whatever measurements I’m comfortable with (feet/yards) to facilitate the flow of the writing. Then I can convert everything afterward to the appropriate unit of measurement. Another excellent idea. Thanks, RJS!

So thanks to my friends for the mental exercise. Overnight I have learned and grown as a writer, and I have JGV and RJS to thank.

‘Til next time, happy writing!

  1. One thing I think about using words like “cramped” or “spacious” is that those get into the character’s opinions about something, which will make the writing more engaging too.

    • Good point, but it’s a vague opinion. That’s why I wouldn’t use that unless it’s something the reader can relate to. Also, in the overall field of experience, one man’s “cramped” is another man’s “spacious.” When I think of character opinion, I usually think more along the lines of opinion that reveals the character. For example, a nonsmoking character might find the light scent of pipe smoke in a library “detestable” whereas another character might find it “delicious” or “warm” etc. etc. etc.
