I had to take a break from writing my bachelor thesis.
So I had some fun, doing some work to estimate the dimensions of the upcoming Lumia 1520 (or whatever it will be named).
Therefore I did the following:
- I took the leaked image and created a photo taken from above, using the perspective correction in Photoshop.
- I made some smaller corrections, to make sure, that the visible tiles are quadratic.
- I went on to calculate the dimensions based on counting pixels.
My results based on a display size of 6 inches: 5.23 inches (13,28 cm) x 2.94 inches (7,47 cm)
Estimated device size with a display size of 6 inches: 6.69 inches (17,00 cm) x 3.50 inches (8,90 cm)
There were some assumptions I had to make in the process, and, as a part of the bezel is hidden due to the perspective of the original photo, divergences have to be expected.
As a comparison, these are the dimensions of the Galaxy Note 2:
5.95 inches x 3.17 inches x 0.37 inches (15,11 cm x 8,05 cm x 0,94 cm)
Let's just assume my calculated dimensions are near the actual size of the device.
In this case, the Lumia 1520 would be 12,5% longer and 10,5% wider than the Galaxy Note 2.
Source of the picture used in the process: Windows Phone Central
UPDATE: If the screen size is not 6 but 5.7 inches which has been rumoured on some websites, then the dimensions would be as follows...
Estimated device size with a display size of 5.7 inches: 6.36 inches (16,15 cm) x 3.33 inches (8,46 cm)
In this case the Lumia 1520 would still be bigger than the Galaxy Note 2.

For what it's worth, I think these estimates are a bit high, which might have been unavoidable given the quality of the image that Cornelius had to work with.
I approached the guestimate game from a different angle: using the known dimensions of the Luima 920, 925, 928 and 1020 to see how much (or little bezel) "overhead" Nokia is using on its high-end Lumia phones and then adding that to the larger screen size.
Assuming that all four models use screens of the same dimensions (Q: is the AMOLED screen really exactly the same size as the LCD?), the screen takes up 98.0mm x 58.8mm. As noted by Cornelius, a 6" 1080P screen is 132.8mm x 74.7mm. The top-to-bottom "overhead" of the 4.5" devices varies from 129mm-133mm while the side-to-side overhead varies from 68.9mm-71.4mm. This puts the minimum overhead for 4.5" models at 31mm x 10.1mm.
Adding those overheads to various screen sizes yields this table. (Note: the width doesn't grow as much as the height because the aspect ratio is shifting from 15:9 to 16:9.)
Screen size Sized like screen of Device size Delta from 920 6.0" First 1520 rumor 163.8mm x 84.8mm (6.45" x 3.34") 1.32" x 0.55" 5.7" Second 1520 rumor 157.2mm x 81.1mm (6.19" x 3.19") 1.05" x 0.40" 5.5" Galaxy Note 2 152.7mm x 78.6mm (6.01" x 3.09") 0.88" x 0.31" 5.2" Galaxy Note (orig) 146.1mm x 74.8mm (5.75" x 2.95") 0.62" x 0.16" 5.0" something reasonable ;) 141.7mm x 72.4mm (5.58" x 2.85") 0.45" x 0.06"
If Nokia can lessen the non-screen "overhead," then the device can be smaller, but they can't add over an inch of height and end up with a phone that's considered anything other than very large.

I think the calculations are not correct, the width will be approximitly 78-80 mm and the height 158-160 mm...
the lower bezel is smaller than he draw, its clear from the photo, look at the black level between the screen and the bezel...
edit: also if i depend on your photoshped image the dimensions will be 153 height and 82 width.... you should always compare with the 1020 image and real dimensions... i think16:9 6" screen has the dimension 132.8x74.7 (anyone please confirm) and that goes perfectly with my results in the first line (78-80x158-160)...

I would have used proportions to figure out the screen size. Obviously none of this is exact but it will give a good idea. This would be the equation:
measured 1020 on screen measured 1520 on screen
measured 1020 in real life X measured 1520 in real life (this would be the "x")
114mm X Xmm
These dimensions are just based on he overhead photo that OP created. I think we all know about what size the device will be so we're all about the same with estimates. We will have to wait :)
EDIT: The proportions won't turn out looking very well I noticed after I posted and tried to edit so hopefully everyone gets it.My goal here is to help out and provide knowledge! Feel free to shoot me a PM

The following calculation backs up my estimation.
Lumia 920 (official measurements from Nokia):
Length: 13,03 cm
Width: 7,08 cm
Screen of Lumia 920 (4.5 inches - 1280:768):
Lenth: 9,375 cm
Width: 5,625 cm
Delta of Lumia 920:
Length: 3,655 cm
Width: 1,455 cm
6 inch screen (6.0 inches - 1920:1080):
Length: 13,28 cm
Width: 7,47 cm
6 inch + Delta of 920:
Length: 16,935 cm
Width: 8,925 cm
Compared to my result from above, which are about the same:
17,00 cm x 8,90 cm
So, if we really get a 6 inch 1520 based on design aspects we know from the 920 or have to be assumed from the leaked picture, I guess, you can expect something like this. However, if there is no or only a small bezel on top of the device (we don't see anything in the leaked picture due to the perspective), it would end up to be a bit shorter.Lumia 920 | Surface RT
