WIP Interior modeling

This thread is all about proper measurements & ideas on improving interior modeling.

I found this book & it’s confusing !

2009 International Residential Code

Can someone point me to the pages that are important for 3d interior modeling ( like wall height & stuff )?

Wall heights and pretty much everything will change depending on the project. Common wall heights are between 8’ and 10’ (2400mm and 3000mm) for North American suburban homes and such. 12’ ceilings are very nice to live in.

Your best bet would be to grab one of Francis Ching’s books on architecture. Starting with Building Construction Illustrated would be a safe bet, or even Interior Design Illustrated. I would go with the first one as it will explain and clarify exactly how spaces are constructed/put together.

You do NOT need the residential code book because that delves into the specifics of a particular location or area.

Typical/common measurements:

Door height: 2000mm - 2200mm (around 7’)
Door width: 28" (i.e. interior door) - 32" (i.e. wide exterior door) or 700mm - 1000mm
Ceiling heights for homes: 2400mm - 3000mm (8’ - 10’)
Floor-to-floor height for institutional buildings: typically 4000mm
Railing or counter heights: 750mm - 850mm, usually about 800mm (about 32")

That’s off the top of my head right now, hopefully that helps…

Standard height at which a light switch is placed is about a meter (From the finished floor to the center of the light switch). In some parts of Europe anyway, sounds like a good enough standard.

You are looking for “Neufert”

At least where I live its the book about default measurements for architects and for me it was a lovely companion during my education.

Don´t be scared by the price, its a book you buy for live, its good to go for at least half an aeon…
Mostly car sizes and some style sizes change over the decades.


I believe you’d made it harder than it has to be. The only thing you need is a tape measure in your hands. Then you can measure your own house, such as the height of walls, doors, tables, etc… Take those measurements and apply them to the models you create in Blender. Easy cheesy :smiley:

For commercial interiors, just google “height of commercial interior walls…” --something like that. It’s what I do when I’ve not been given proper dimensions.

How do I read this ? is this inches, feet or meters ?

Do you think someone would want to live in a 8x9 feet flat? Or 8x9 inches…?

I am a bit astounded that you can’t figure this out on your own. Honestly its not that hard. I could tell you but am not in the mood to spoon feed.

-Hovercraft posted just before me but he is using the logical thinking that will get you your answer. Just apply simple common sense reasoning.

I know im really out of brain fluids, is it by any chance meters ?

the ones highlighted in bold should help you out. but the dimensioning is weird because he seems to use two different measure but you can figure them out quickly

arexma is Neufert good? Is it still valid?

Great news!

Depending on the drawings you get, sometimes they are in metric (typically mm) or imperial (feet and inches), which is why I put approximations for each.

Regarding the scanned plan, if you know the ballpark widths of typical doorways and wall thicknesses, you should be able to figure out units very easily.

Again, unless you’re creating images for a specific space/building/interior (i.e. if you get contracted to do some arch. viz), then don’t worry so much about the exact dimensions of space. After all, there’s nothing stopping you from making ceilings a bit taller, or walls a bit thicker, or windows a bit larger/smaller. There are doors that are 7’ tall and doors that are 12’ tall, so use your imagination. That’s how you get nice, interesting, unique spaces/interiors, follow?

The only confusion is in regards to whether the main units are yard or meters, but the sub-units give it away. There is no way a bathroom countertop is 7’ deep, unless people are bathing in it as well. And please, next time, look at the forum options and post in the appropriate one.

That was what I was trying to hint at and hoped she would get that. judging by the wall thickness and doorway width I would say the smaller measures are in centimeters and if he stayed with metric units than the bigger ones would be meters.

When I was studying mechincal engineering mixing meters and millimeters in one drawing would have earned you a fail. My teacher was pretty strict on that I assumed the same kind of reasoning would apply to building plans. Most building plans I see at work stick to that standard too. they are either in m or mm no mixing. So I was confused with the architects unit swapping

They adapt it every once in a while, there might be better ones, but I doubt there is much difference between all those books.

To be perfectly honest, I used the 68’ print from my gramps (architect) during my education and it was still pretty accurate and sufficient. As I stated not much changes, besides the measurements for a car parking slot for instance, or the size of a washing machine or a TV set. You wheren´t able to park a 90´s car in a 60´s slot (european cars) but the rest…
It has pretty much everything in it, from the height where you put an urinal for adults or children to the average heights for doorknobs, doorwidths, how much room you need around a pooltable to be able to play with audience, what the minimum mounting height of kitchen wall cupboard should be so the average euorpean housewife, or houseman for that matter doesn´t bump ones head.

It was one of those lexica which simply augments your common sense. =)
