because inland winds provide much more power than sea winds.
The only difference is inland winds are gusty, you always want to take both the average and gusts in to account when kitesurfing. Ideally you rig small enough to be comfortable in the gusts yet big enough to handle the average.
For me, a 12m kite + TT works in the 11-25 knot range. So if I think it'll be about 15-20 with gusts up to 25 I'll take a 12m.
Meanwhile my 17m kite + TT works in the 9-22 knot range. So if I think it'll be about 12-14 with gusts up to 18 I'll take the 17m.
The OP has said he's looking at 10-15 knot winds, these are borderline winds for 12m, especially 80 kg people. I have no clue why people would be advising him to get a 12m and compensate with a door board. While that might work, he would have much more fun and an easier time on 14-17m kite and a normal board.
