How does the screen of Nexus 7 compare to Retina display iPad offers?
- chrisbroadfoot 14y agoIn terms of density, it's between iPad 2 and iPad 3.
- telcodud 14y agoiPad 2 has a dpi of 132, Nexus 7 213, and iPad 3 264. Nexus 7, while not "retina", is closer to iPad 3 than iPad 2.
- pooriaazimi 14y agoNo. You usually hold a 7" tablet closer to your eyes than a 10" one. So, for its pixels to appear the same to your poor eyes as pixels on an 246 ppi iPad 3, it must have a pixel density of 290 or so.

- pooriaazimi 14y agoI think what I said is true. I can't understand why it's been downvoted...
- codeka 14y agoI didn't down vote, but how did you come up with 290 as a value?
- pooriaazimi 14y agoI actually did the math in my head (Thales) and thought 290 might be just about right, but if you want to be more accurate, use http://bhtooefr.org/displaycalc.htm http://bhtooefr.org/displaycalc.htm . The number at bottom-right is the distance "at which individual pixels will no longer be distinguishable", a.k.a Retina. Retina iPad 3: 2048x1536, 9.7" display, distance: 13", PPI: 263 A contrived Retina Nexus 7: 1700x1130, 7" display, distance: 11.75", PPI: 291 (I adjusted screen resolution so the distance is about 11.5") I tried to do the math myself, but failed miserably. This article on TUAW has some formulas: http://www.tuaw.com/2012/03/01/retina-display-macs-ipads-and-hidpi-doing-the-math/ http://www.tuaw.com/2012/03/01/retina-display-macs-ipads-and...
- DominikR 14y agoAnd on what do you base your assumption that a Nexus 7 is held closer than an iPad? All those numbers presented seem to be tailored to fit your "calculations". (11,75" vs 13" .. how do you come up with that?)
- pooriaazimi 14y agoThe 13" inch, I measured (really! with a tape measure - just before posting that comment). And as I said, I based my assumption on myself and how I always use my iPad and when I used a friend's Galaxy tab a while back; We actually talked about it and how you hold it closer than my iPad. Not a lot, bu by an inch or two. So, that's how I "came up" with 11.5" and tailored the resolutions to give me a number close to it... :)
- dasil003 14y agoI didn't downvote you, but I'm skeptical of the claim. They're both hand-held devices. I don't generally hold my Galaxy Nexus closer to my face than my iPad.
- pooriaazimi 14y agoI personally do hold an smaller tablet closer, but I might be wrong and most people don't do it. You're the living example :)
- jarek 14y agoFYI: I downvoted you because telcodud was explicitly not making a claim that Nexus 7 is "retina," and in your retina-calculation math you completely overlooked the actual (and correct) answer to mycodebreaks' question: > Nexus 7 [is] not "retina" > Nexus 7 is closer to iPad 3 than iPad 2. What you did end up saying is correct but unrelated to the post you were disagreeing with.
- pooriaazimi 14y agoI absolutely don't mind a downvote; I was just confused because I thought I was horribly wrong... My point was that it's not closer to iPad 3, it's really between iPad 2 and iPad 3. Anyway, it's not important :)
- jarek 14y agoWell, it's between iPad 2 and iPad 3, and probably closer to the iPad 3 like telcodud said... you're both right to a degree, but the tone of your initial comment rubbed me the wrong way, sorry. I gave you back an upvote :)
- badusername 14y agoYou don't have to hold it any closer. I assume that there would just be less on the screen. Better to optimize for reading comfort than packing as much as possible on to the screen.
- brohee 14y agoYour lap is closer holding a smaller tablet? That's awesome!
