I bought a 'vimpel' yesterday, and on the package is a table:

Height          Length              Length
of pole         of flag             of pennant

3-4 m           100 cm              150 cm
4-5 m           150 cm              200 cm
5-6 m           150 cm              250 cm
6-7 m           200 cm              300 cm
7-8 m           200 cm              350 cm
8-9 m           225 cm              400 cm
9-10 m          250 cm              450 cm
10-11 m         275 cm              500 cm
11-12 m         300 cm              500 cm
12-14 m         350 cm              600 cm
14-16 m         400 cm              700 cm
16-18 m         450 cm              800 cm
18-20 m         500 cm              900 cm
20-22 m         600 cm             1000 cm

This works for Dansik flag and pennants only, I guess. Then again maybe not. In any case, it gives following rules:
pole height = 4x length of flag
length of pennant = 1.5x length of flag

Of course, much approximated. I'd say this seems reasonable (for the kind of flying the Danish flag is typically used, this does not work for, say vertical flag hoisting favored in Central Europe, the knattefane (sp?) of German surroundings and other "untypical" flags).

I guess it is Danish-only - I seem to remember one of our members comparing this, and noting that Danish flags are quite small on a pole.

The flag-to-pole ratio is, regulated, while the pennant-to-pole ratio is a recommendation from the flagmaker only.

ED: From an question referred to FOTW:

What is the proper height of the ensign relative to the water when displayed from the stern of a single masted sailboat?

We have been told it should just be touching the water when at rest.

Touching the water? I wouldn't think so, but maybe. The rule I've seen in U.S. sources is that the ensign should measure at least one inch on the fly for every foot of height of the mainmast for a sailboat, or for every foot of overall length in the case of a powerboat. "At least" in this case provides for one to round up to the next commercially available flag size. I believe this is in the NY Yacht Club "Yacht Routine," Chapman's Modern Piloting, and similar sources.

Proper height does not depend on distance to the water. Ensign's height must be relative to boat's length, and it should not touch the water at all, so, if proper height the ensign gets too close or touches the water, the mast should be changed.
