Actual size does not display as actual size

Hi All,
Like many of you at one time, I am new to Macs. I have a new iMac and 15"MacBook Pro and observe the same problem on both. I open a document with a default view of 125%. When I go to View/Zoom/Actual size, the document goes to 100% and the onscreen size changes. HOWEVER, the actual size is really at about 75% (one inch on the document ruler actually measures about 3/4 inch). The closest I can get to actual size onscreen is to use 125% but that only approximates actual size.
Any ideas??????
I often print out titles, sayings etc which are used by my wife in her scrapbooking and therefore, it is important to know the actual size!!!
Thanks,
phrankxm

There is no setting allowing us to use seriously an intermediate setting.
Look at
http://discussions.apple.com/thread.jspa?messageID=10015516
where Magnus Lewan gave a tip allowing documents to default to such a value but if we have to change the zoom factor for this or that reason we aren't allowed to return to the custom value.

The terms "actual size" and "100%" are misnomers. To give an example, if you open an image in Preview and choose "actual size", it will display your image at 1 pixel on the screen per 1 pixel of image. The size of the image you see on your screen will be different depending on the resolution and size of your screen. It does not vary with the resolution of your printer or the dimensions of the paper you have chosen or any other printer settings. The size you see on the screen has nothing to do with the size of your printout. "Actual size" is not really "actual size", as you have discovered.

Turn on the rulers that are built into Pages. They are not "actual size" either but they'll show what the size will be for the paper size you have chosen.

Welcome to the forums. 🙂

As you have discovered screens appear all sorts of proportions relative to what is shown. The computer can't determine how big the screen is physically, only how many pixels it displays and the pixels can be large or small but by convention are considered 72 per inch which harks back to the days of the original Mac when it was indeed to size.

To match your wife's scrapbooking, use actual measurements which you can get on the toolbar ruler:

+Menu > View > Show Rulers+

or in the Inspector

+Inspector > Metrics (6th tab little ruler) > Size+

Thanks Badunit,
I appreciate your response. I don't like the response BUT it is what it is 🙂. Seems to me, Apple should redefine the actual and 100% modes - if they are not actual and not 100% then they are useless as labeled!
I did not have an issue with printing since I new it would print in accordance to the rulers, page setup etc. Actual and Magnification settings are for display purposes and are just plain wrong. Since I often use actual to see how it will show up on my wife's scrapbooking pages, I will have to 'fudge' things when working on the macs.
Thanks again.

Peter/Badunit/Yvon - Thanks to all for your excellent assistance. I will follow your advice to correct the problem. The only thing that bugs me is that we have to do a workaround for such a simple thing. Seems that something so fundamental should be built-in. (Don't tell anyone I said this, but, Microsoft does not have this issue - actual size/100% is just what it says - actual size in the display).
Thanks again.

Peter,
I had been a PC person for too many years!! The Microsoft Word program always gave precise 'actual' size displays with any monitor and any screen resolution. Windows always knew the screen/display set up and the monitor screen physical size - from there, just scaling would get you the precision needed. I am not a programmer, so I can not give the details but as a user, over many years, and with many different displays on desktops and laptops, they always got it right. HOWEVER, I love my MACs !!!!!!
Note: your input was easy and simple to implement. A magnification factor of 132% was just about right for my setup on the 24" iMac. Be interesting to see what it will be on the 15" MacBook Pro!!
Thanks for your help.

I agree Peter - Microsoft did not always get it right - there was always a lot to desire from Microsoft - but at the same time, they did get some things right.
I checked one of my PCs to make sure I had it right and it was as I described. I did not try different displays but it always worked right on my desktops and my laptops. However, I do remember that when I connected my laptop to my TV, actual was not actual but in that case, the laptop had no input as to the characteristics of the second monitor (TV).
I will follow your advice and provide Pages feedback.
Thanks,

Hi Peggy,
As far as I know, Windows knows all about your monitor when it detects the connection and it knows the display mode (pixel X pixel) from its own set up and therefore can easily determine how to get actual size. However, it does not get this same information when it is connected to my plasma TV!!

As far as I know, an application may get the resolution (for instance 1920 * 1600 pixels) but it can't get the size of these pixels.
So I can't guess how it may determine the zoom factor giving a true 100% display.
Just as examples, I'm aware of 24" and 26" displays delivering both 1920* 1600.
The app can't take care of that.
The only soluce would be that it maintain a table of available devices with their pixel size.

I doubt that 100%. I'm on a Mac now, so I cannot check on a current Windows system, but there is no way Microsoft could know the size of the pixels of each screen you attach to every kind of PC.

It may seemingly work on some obscure screen which happens to match, but it cannot be a rule.

If we look at it historically, it was actually the other way round. Windows never ever showed 100% correctly, as they had no idea of the connected screens. However, early Macs had complete control over the attached hardware, so their 100% was really 100%. As time went on, Apple realised that it was impossible to keep this match, as users required higher resolution per displayed inch, and pixels became smaller.

100% is still some kind of standard for a certain number of pixels. If you look at MS Word, Pages and Adobe products on a Mac today, their "100%" are all the same size - none of them corresponds to the physical size of the printed paper though.

I am running some checks with some IT friends to get some more details. However, it does appear that my desktop Dell, working with a 17" LCD (not the original monitor) gives a display where actual/100% is 100%. However, my Dell laptop PC is only close (I previously thought it was 100%). It is about 95% on close inspection.
I agree with you all re the need to know pixel size BUT that is not a difficult thing to calculate given the pixel setup and the screen size. Simple inputs can lead to simple conclusions and allow for accurate displays.
On the other hand, I may be only one of a few people that has a use for actual size displays.
