    Hello all,

    I know there are a lot of smart ppl here.

    So, can someone tell me which device has more total screen area?

    I want a bigger screen than my Z30, but I don't want to carry a tablet.

    Definetly the note at like 5.7 inches vs the 4.5 of the passport and 3.5 of the classic.

    You are talking about diagonal measurement. Wouldn't the extra width of the passport make up for the lost diagonal inches?

    Anybody know the total area of the screens of both phones? (not diagonal measurements)

    Assuming the poster above was right about the diagonal measurement of the Note 3 screen the total screen area is about 13 square inches for the Note 3 and about 10 square inches for the Passport.

    since 1440x1440=1920x1080 the no of pixels is exactly the same. Compare pixel density. To see how much bigger one is than the other.
    386ppi vs 453ppi
    You need 453 BlackBerry screens to cover same area as only 386 galaxy's. Galaxy is 17% bigger

    It does not work like that. The dot pitch of each pixel could be different. The surface area of the Galaxy Note 3 is 13.87" vs. BlackBerry Passport 10.11" so the Note 3 is 37% bigger surface area.

    No - It does work like that.

    I'm guessing you used diagonal sizes 5.7 and 4.5 and used pythagoras to get the height and width but 5.7 and 4 and a half are approximate.
    Might be 5.65 and 4.6?

    The ppi figures are to nearest pixel so I used them as the margin of error should be less.

    A square inch of passport display holds 453 Pixels.
    A square inch of galaxy 386 Pixels.
    Where are the extra 453-386=53+14=67 pixels.
    That's 67/386 =17.3575% more screen area.

    Of course - provided the ppi values I used are correct and haven't been miscalculated from the diagonal measurements - I got the from gsm arena or somewhere like that.

    First off 1440x1440 =/= 1920x1080.

    Also, you can't use PPI to measure total screen area. You're wrong.

    You can.
    The problem in my method in that ppi is linear not square. I needed to square the ppi values to get ppsi. Then get. 37%

    Thank you.

    This is exactly the info I was looking for.

    One last question, whats the area of the Z30 as it compares to the two above? In other words, how much screen area will I gain going to a Passport? (I really don't want to switch to an Android.)

    10.47", however because the resolution is different you can't really compare the two properly. For example, because of the low PPI on the Z30 text content becomes unreadable or severely distorted as it scales to smaller points. On the Passport this won't be an issue. This means that technically Blackberry could scale the UI elements on the Passport to give you more usable screen space. At the very minimum the Passport is guaranteed to be able to display just as much content as the Z30 both horizontally and vertically. In fact, it will display 160px more in both directions.

    For the simplest analogy think of it like putting two Z30s side by side (720+720=1440). That's basically how much useful screen space you will have on the Passport plus another 160px vertically.

    If you do all the math and assume there is no scaling change to any of the UI or textual elements that appear on screen everything on the Passport will appear approximately 53% smaller than on the Z30 (about half size). This will allow you to display slightly more content on the Passport than two Z30 displays put together side by side on a display that is only 4.5" diagonal and with a tad smaller surface area than the Z30.

    That's wrong. It's one line of pixels that pack 453 dots on the length of one inch. A square inch of Passport display holds 453 * 453 = 205,209 pixels.

    Now let's just do the math, I have an excel sheet for years now that gives me the exact numbers.

    BlackBerry Passport
    4.5" diagonal @ 1,440 * 1,440 = 2,073,600 pixels
    PPI: 453
    Screen dimensions: 3.18" * 3.18"
    Screen surface area: 10.125 squareinches

    Samsung Galaxy Note 3
    5.7" diagonal @ 1.920 * 1080 = 2,073,600 pixels
    PPI: 386
    Screen dimensions: 2.79" * 4.97"
    Screen surface area: 13.883 squareinches

    Surface area comparison:

    13.883 / 10.125 = 1.37116
    -> the Note screen, as denjah said, is 37.12% bigger in terms of surface area size.

    Yet its shorter display side is always a whopping 0.39" shorter than any of the Passports display sides.

    Guys why are we even talking about ppi? The op asked for AREA of screen space. That's a simple length * width calculation.

    I just made a thread with a link to a comparison between Note 2 and Passport:

    http://forums.crackberry.com/blackbe.../#post10616482

    Not to make an unfair comparison between an older and newer phone but there are specs/features on this list that I personally didn't know of (if this list is at all accurate). More info on Passport specs/features, that's my reason to make that thread/post.
