What Size Should I Make My Virtual Doors?

What Size Should I Make My Virtual Door?

This is a question I often get so I did the math. Converting the real world standard door sizes (based on US standards of 6’8″ high, 1 1/2 – 1 3/4″ thick, & 28″ (a narrow interior door) to 36″ (a wide exterior door) wide and converting that to meters we get:

2.03 meters high x 0.7112 to 0.9144 meters wide x 0.0381 to 0.04445 meters thick.

If we actually use these real world dimensions most avatars won’t be able to pass through them. Avatars average much taller than in the real world. By multiplying any standard sizes by 1.25 we get a more usable size for virtual worlds while keeping our overall proportions visually accurate.

So, multiplying standard door sizes by 1.25 we get 2.54 meters high x 0.889 to 1.143 meters wide x 0.047625 to 0.0555625 thick.

Of course, we don’t want to mess with that kind of complicated math so we can do a little rounding out. In addition, we also need to make some changes to get the center of the prim on the hinge edge so our door scripts can rotate our doors properly. That means doubling the door width and adding a few other settings. We also need to adjust our texture settings so that our textures will properly apply in typical scenarios.

Here’s my standard door sizes and settings that I frequently use:

Interior Doors:

Object Tab:
Size:
X 2.0 (32″ wide – can use 1.8 to 2.3)
Y 2.5
Z 0.05

Rotation:
X 90
Y 0
Z 0

Path Cut:
B: 0.125
E: 0.625

Texture Tab:
Horizontal Scale: 2.0
Horizontal Offset: 0.5

Exterior Doors:

Object Tab:
Size:
X 2.3 (36″ wide – can use 2.0 to 2.3)
Y 2.5
Z 0.06

Rotation:
X 90
Y 0
Z 0

Path Cut:
B: 0.125
E: 0.625

Texture Tab:
Horizontal Scale: 2.0
Horizontal Offset: 0.5

And, in the case it ever comes up, doorknob heights are 36″ to 48″ high. That’s 1.15 to 1.52 meters high in virtual world math. I generally use 1.25 meters (44″).

Center door hinges (for 3 hinges or halfway between the hinges if using 2), light switches, thermostats, towel bars, shower controls, and cabinet splashes should also be centered at the same height you use for your door knobs. By standard methods anyway. Your virtual world creations should be whatever tickles your fancy bone but it’s sometimes good to know the standards.
