One of the benefits of Ryanair operating a streamlined fleet of aircraft is that there are very few competing aircraft types or cabin layouts.
I have produced a couple of cabin layout plans which show the seat positions relative to window locations so you can see where the window blanks are located.
Starting with the ubliquitous 737-800 which has been checked using several control points along the length of the cabin for accuracy. The following 737-Max 8200 has been checked using only Ryanair's seat map and so at this time should be treated as more indicative.
Boeing 737-800
A single Economy Class cabin accommodating 189 Zodiac Z110 slimline seats. Some aircraft are fitted with older Weber C100 seats
Seat width: 17.7"

Front row seats offer additional legroom
The seat backs are fixed and do not recline
