If we account for the boundaries it's probably a total right around 45 km 2. Skellige Isles & Ocean: 28.9 km 2 (11.1 mi 2) Measuring the map from end to end (so including small restricted boundaries of each world map) gave me the dimensions, from which I got:

Here are the rough calculations I did for the other maps: Mentally, I just tack off 10-15% of the sizes listed below. Accounting for those is a little difficult because the invisible border is not made up of straight lines. Note that this measurement (and the other map measurements) do not account for the restricted area at the border of each map where Geralt refuses to walk to. This is about 53% of the Novigrad/Velen/HOS total map size, and about the same size as all of the land area in Skellige (~35-40% of the full Skellige map, definitely a bit larger than Ard Skellig).

The map is approximately 3085m X 2579m, or 7.96 km 2. This means that the total map for The Witcher 3: Wild Hunt is nearly 6. New adventures for The Witcher are made with the Djinni Adventure Editor that comes with the game. The Night City map is estimated to be about 4 kilometers across by 6 kilometers in height, or 24 square kilometers overall. Posted: 1:28 pm Students from Warsaw University in Poland have created a fully detailed, to-scale map of The Witcher universe's continent, and it's a doozy that shows off the scale. I measured the in-game distances from N-S & W-E (the mini-map distances). Text size increase for high resolutions (Image credit: Jegahl).
