Doing a little revision to a previous blog post: The front is really not 1,200 kilometers long – The Dupuy Institute
Lot’s of people throw out the figure that the front line is 1,200 kilometers long. Not really. The length of the border of Ukraine (pre-2014) with Russia is 1,974 kilometers (1,227 miles). This is the land border. The length of the border with Belarus (which I do not think is going to re-enter this contest) is 891 kilometers (554 miles). The entire coastline of Ukraine is 3,783 kilometers (2,351 miles). I think this last figure includes Crimea.

But, they really are not fighting from Chernihiv to Sumy and have not done so since April 2022. This is a large portion of that 1,200 kilometer figure. They do share a border with Russia so Ukraine obviously has to protect these areas, but there really has not been any fighting in these areas for over two years. We do not expect that will change.
Second, they really cannot do major operations along the Dnipro River from Kherson up to the Kakhovka Reservoir. There was, in the best of times only three bridges across this river, and I gather that number is three less now. This creates supply issues and with all the drones, missiles and air support, hard to see how this is corrected. No one has yet to do any major military operations across the Kakhovka Reservoir. This takes a significant chunk of miles off any active front.
Therefore, for all practical purposes the active front runs from the western border of Kharkiv province over to Kupyansk, down through the Donbas and then through Zaporizhzhia Oblast to the Kakhovka Reservoir. This is about 700 kilometers, vice 1,200.
Here are the measurements we currently have for the front line trace (someone, please check us):
From Kupyansk to Bakhmut: 153.09 kilometers
From Bakhmut to Vuhledar: 133.64 kilometers
One kilometer is 0.62 miles. Therefore an active front of roughly 700 kilometers or around 435 miles.
