I just checked Lochcarron's site, happily they give the repeat, and for the Robertson Hunting Ancient in medium weight they give the repeat as 13 inches.

Of course due to the nature of that tartan it gives the impression of a repeat half that size, 6.5 inches, which is common for medium weight tartans.

13 inches is still a big repeat if you're pleating to the stripe that occurs half as often as some of the other stripes. For example with MacKenzie the white stripe occurs on every green but the red stripe only occurs on every other blue, which is why military kilts in MacKenzie pleat to the white stripe.

So with your Robertson Hunting pleating to the red stripe means, in effect, pleating to a 6.5 inch sett which is commonplace. Pleating to the white stripe wouldn't work; you'd end up like Hunting Stewart with the pleats alternating between two colours of stripes, in your case red and white.

Hunting Stewart is notoriously difficult to pleat because both the red and the yellow stripes only occur in every other repeat of the underlying pattern. Thus the military kilts in Hunting Stewart have the pleats alternate between red and yellow.

But on MacKenzie, Hunting Robertson, and Hunting Stewart there are black stripes which occur more often than the red, white, or yellow over-stripes. That's how I had my Hunting Stewart kilt pleated.
