How Big Are 1/700 Scale Portholes?

[Andrew Gorman]

I'm finishing up a roughly 1/700 scale ship-like vessel and need to add some portholes.  As a naval dummy, I have no idea how big the real things are.  18"  seems plausible and scales down to .025 inches, or roughly #70 drill.  This looks a little small.  How big do the portholes usually end up on a 1/700 model, or how big are the real things?  My very general prototype is an 1890's warship.
Thanks!

Here's a photo taken on the USS Pennsylvania circa 1940:


This is HMS Dreadnought, but the porthole size probably wasn't that much different from an 1890s pre-Dreadnought.


As to diameter, 16" glass was on the large end of the scale for warship portholes and was fairly standard.

So I'd go for the #70 drill, but if you feel they look too small then drill them larger.

Grab that bugger down in the lower right, he's just wiped his arse and he's flinging the paper out the porthole!

Hi Andrew
the glass size is 9"-12" diameter which works out at 0.32mm - 0.43mm dia.
Hope this helps

I guess  about 0ne seven hundreth of the size of real ones    (sorry couldnt resist that)

I spent a long time at sea and portholes came in many different sizes dependant on where they were(  cabin,store,machine shop etc.) so 1/700th the size should do it.

Thanks for the responses to my clueless question, but 1/700 ships are unknown territory for me.  The photos were especially helpful.  The answer is, the portholes are really, really tiny!

Everything in 1/700 is really, really tiny!

even the ships are tiny...

Tiny, but not THAT tiny.  Figure any ship from a destroyer to a battleship is going to be the size of a 1/72 fighter plane, from a Fokker Eindecker to an F-101. The only difference is you need lots of tiny details to make the model work.  I'm having fun with it, at least.

Heres a link to someone who packs a lot more detail than I can into these little ships- check out anything titled "Building..." for (for me) a real education-

Absolutely right Andrew. I always take time to admire the small scale ship models at shows. Especially like the pre-Dreadnaughts. Some even have crew figures - I know they are tiny bits of styrene with a dk blue bottom half, white top half but they just make the model
