    Can some one tell me the formula to scale a model to full size without knowing the scale the model was build on??? I am sure there are programs for this, but I would prefer to learn the "old school" way...a pencil.

    Thanks in advance

    When you say you don't know what scale it was built to, do you really mean that? I mean, do you know, for instance, how long the 'real thing' should be?... Is it a model of, say, a 40 foot boat?
    If you really don't what scale the boat was built to, then there's no way to know how big the 'real thing' should be I'm afraid.

    Without knowing atleast one of the full sized measurements I can't see how it would be possible.

    You can measure a standard item (door, people, ceiling height, etc) a find a average scale. This is not very accurate.

    Make a paper man with a strip of paper that fits the boat nicely, then assume the paper man is 1.85 meters, and measure the paper man to get the scale!

    Without real dimension...nothing is possible.

    To extrapolate you will need the scale

    your best bet is to decide how big you WANT your boat to be. then you can measure your model, do the division, and determine what the scale is.
