Size of DS1:
Imperial Navy:Now as can be seen from the above, Death Star is not perfectly spherical… this however is likely just a distortion caused by the format. If so, then 181 px height is correct for the entire diameter of the Death Star. With band being 11-13 px, it appears that the Death Star is some 135 – 160 km in diameter. Trench itself is some two pixels, and using value of 1272,96 meters, Death Star would appear to be some 115 kilometers in diameter.
Since I am too lazy to do any more measurement, I will just take the midpoint value and assume 135 km Death Star I (which is also almost exactly the same as the arithmetic average of the three values, which is 137 km).
With diameter of 135 kilometers, Death Star I has the surface area of 57 255,53 km2 or 57 255 526 110 m2.
Using value of 57 255 526 110 m2 for the surface of the Death Star and one gun per 5 625 square meters, we arrive at the value of a total of 10 178 760 guns. Absolute lower limit would be 57 000 guns, with higher lower limit being between 101 800 and 229 000 guns.
In total, Imperial Star Destroyer has 70 – 72 heavy turbolasers.
With all of this in mind, median number of 28 000 ISD-equivalents is the most likely one.
Using median number of 28 000 ISD equivalents would result in 154 fleets, with a total of 154 super star destroyers, 6 160 Imperial Star Destroyers and 15 400 frigates and corvettes. Thus Imperial fleet would have a total of 21 700 warships.
High end of 280 000 ISD equivalents would give 1 540 fleets, for 1 540 SSDs, 61 600 ISDs and 154 000 frigates and corvettes. This would give a total of 217 000 warships.
Low end of 3 600 ISD equivalents would give 20 fleets, for 20 SSDs, 800 ISDs and 2 000 frigates and corvettes – a total of 2 820 warships.
