Two-stage missiles

[Person012345 (OP)]

Just had a quick question about two stage missiles that I wanted to check before I designed an entire launch system around a missile that won't fit it:

When calculating the launcher size required for a two-stage missile, does it take into account the size of both stages, eg. Stage one is size 5 and stage two is size 5 therefore you need a size 10 launcher, or does it only take into account one of them, eg. in the above example a size 5 launcher would be needed. Are there any additional important or unintuitive mechanics about multi-stage missiles I should be aware of?

Your boost stage needs to have enough room for the second stage plus any fuel/engines/etc. So if your booster is size 5 and your payload is size 5, you need a size 10 launcher.

When you design the booster stage and add the second stage, the missile design takes it into account and lists the total size for the missile in the design parameters window.
