I don’t know how you all are holding iPads and iphones that you think there’s some huge difference. I don’t hold an iPad with an arm perfectly outstretched, and I don’t hold a phone 4 inches from my face either. Both are handheld devices and held at basically same distance.
You keep coming here and arguing, even after multiple people have addressed the errors in your statements about this topic.
Yes, people hold iPads and iPhones at different distances. I’ve done physics research in the past on iPhones and iPads on multiple use cases, including distances held, the amount of torque required at the elbow and wrist joint to hold an iPad given certain weights, etc.
There are two main reasons why there is a natural tendency and a need to hold a device with a larger screen farther away vs. a device with a smaller screen: 1. The content on the smaller device is generally scaled smaller. That means most things are smaller on the screen: text, buttons, icons, etc. The eyes have to focus on those elements and the smaller those elements are, the more difficult they are to see at farther distances. 2. Field of view. The larger the screen, the farther away from the eyes it has to be because of the limitations of field of view. The eyes naturally pixelate in their periphery. So a larger screened iPad needs to be held farther away from the eyes for all of its content to be viewable without peripheral pixelation.
There are tables that include optimal viewing distances for a series of different screen sizes.
None of this means that everyone always at all times holds their iPad farther from their eyes than an iPhone, but the physical size of the screen necessitates it be held farther away for optimal viewing.
Regardless of any of this, even at the same viewing distance as my iPhone, I just did a test of two of the same websites and I can’t really see more pixelation on my M4 iPad 13” Pro vs. my iPhone 14 Pro Max.
