It is not my fault that you can't provide basic information about the bug you're allegedly experiencing, while all the other few hundred thousands of users have no problem. What you've told me so far is utter rubbish.
Also, this extension is aimed at developers so I will assume everyone that contacts me and doesn't say otherwise is one. Being a developer and not knowing what a window's viewport is or how to use Chrome's Developer Tools to get the innerWidth, innerHeight, outterWidth & outerHeight of the window (or the devicePixelRatio for that matter) is shameful, to say the least, and I will not waste my time teaching you what those are - you have Google for that.

FYI, Windows 7 won't let you make a window larger than the screen resolution so you could easily grab the title bar and move the window higher on the screen to see the bottom of it (not that this has any relevance, but to make you realize how stupid you sound when you say the window is so huge, it stretches beyond the bottom of the screen).

I can't fix something I can't see!
They look ok to me. Here's what I did:
1) I re-sized the viewport to 1366 x 768, which gave me a window size of 1382 x 857.
2) I zoomed in at 150%
3) The tooltip reported a viewport size of 911 x 512 and the same window size as before, which is correct. Window's size doesn't change when zooming while the viewport does, as it should. When zooming in, the page's pixels count doesn't change, just their size; a CSS pixel will be rendered at 150% of it's original size, meaning that  in the original area of 1366 physical pixels will fit less virtual zoomed in pixels. The formula for this is
"physical size" / "zoom"
which gives
1366 / 150% = 1366 * 100 / 150 = 910,(6)
768 / 150% = 768 * 100 / 150 = 512

Everything is much clearer when you increase the zoom to 200% and you'll notice that the viewport size is half than the original; you double the content size and only half remains visible.

Anyway, if you still think this is wrong, then you should send a bug report to the Chrome developers because the tooltip displays the window.innerWidth and window.innerHeight values, exactly as they are reported by Chrome. :)

If you don't get the same values as I did, please reply to this message with the exact values that are displayed when you follow the steps I listed above.

Hi Gail,

You can click on the extension's icon and then "Edit presets". On the page that opens you can add new presets, remove or re-order existing presets. The one you have used is for tablets, which means it re-sizes the viewport (the area in which the page is rendered) to the selected dimensions, resulting in a window slightly larger (the chosen dimension plus the width and height of the window's borders).
If you add a new preset and you want to re-size the entire window, make sure you check "Window" under the "Resize target" group. Also, please note that the extension most likely won't be able to make the window larger than your screen's resolution due to operating system limitations.


Best Regards,
