The indicated size of the viewport does not match the anticipated value

My goal is to incorporate responsive web design into my project and I have specified the viewport size as follows:

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0" />

I expected this setting to adjust the viewport width based on the device's actual width. For example, a Samsung Galaxy Nexus with 720px width should result in a viewport size of 720px. However, it seems that the reported viewport size is only 320px, half of the actual width.

I am utilizing CSS media queries and I have verified using alert($(window).width());

The code looks like this:

<link href="css/mobile-medium.css" media="all and (min-width: 320px) and (max-width: 479px)" rel="stylesheet" type="text/css" />

Instead of:

<link href="css/mobile-large.css" media="all and (min-width: 480px) and (max-width: 767px)" rel="stylesheet" type="text/css" />

I'm confused about why this discrepancy exists! The issue persists not just on Android devices but also on iPhone 4(S).

How can one effectively match different css media queries when the reported sizes are so misleading?

Answer №1

A potential reason for the issue may be related to a higher pixel density, specifically the -webkit-min-device-pixel-ratio property. One possible solution is to explore using media queries in CSS as recommended here: Media queries in CSS

For further information on this topic, you might find this link helpful. However, I must admit that it might be beyond my current expertise:

Answer №2

It seems that browsers on high dpi devices like the galaxy nexus, iphone 4, and the "new iPad" (ver3) adjust their viewport width to render CSS effectively, making it appear smaller than their actual resolution. This helps prevent larger websites designed for screens larger than 10.1 inches from displaying in full scale on devices like the new iPad.

I recently heard about this concept on a podcast, possibly the Shoptalk show with guest speaker Matt Marquis.
