Font size in pixels

I have UIFont.systemFontOfSize(16.0)
I want to know the font size pixels on html
As #CynicismRising answer:- Point sizes are defined as 1/72 of an inch. That is, a 72-point font is approximately 1 inch from the lowest descent to the highest ascent. So the maximum height of a glyph in a 72pt font is about 1 inch.

By design (!) I have two lines title text which I cannot break:
JustWord

On big iPhones (6 and 6 Plus) text works great,but when I test on smaller iPhone (5 or less) it looks like:

I cannot find a way how to shrink the text in UILabel.Cutting and truncating are not possible in my situation.

Please try adjustsFontSizeToFitWidth: property for UIlabel. I have tried this and font is setting in one line and font size is automatically adjust.
The two principal ways to do this are to set a minimum font size or a minimum font scale.
I have 2 buttons with the same width and height, also y-Achse centered. They differ only from text length. With iPhone 5, 6 and 6+ they look very well. But with iPhone 4s one button will do not more have the same front size as the other one and it is text will be not more centered. My question is if there is a method to adopt the font size of the 2 buttons so they will take together the same font with small value of font size of one button.
If I understand correctly, you want to use the same font size for both buttons, even when one of them has to reduce the size for the text to fit it.
Use something like this to reduce the size of the font on each button, until an appropriate size is found for both buttons. Take the minimum of the sizes you found, and use it on both buttons.
What's a clean way to use SKLabelNode's fontSize to map to pixels? I'm trying to place text inside a box that fits in a fixed box proportionately.
According to apple's documentation, 1 font point is equal to 2 pixels.
For example, a 90 pixel font is equal to mytext.fontSize = 90 / 2

How to calculate the pixel width of a String in JavaFX?
(4 answers)
Closed 8 years ago.
How does one calculate the number of visible characters in one row (without horizontal scrolling!) of a TextArea in JavaFX depending on the width of the area?
I use a monospaced font, so all chars have the same width. Is it possible to calculate the width of a font char by its font size?
Yes it's possible to calculate them.
Even with a custom font.
You can use the FontMetrics class.
Font font = Font.font("YourFont", 14);
FontMetrics fontMetrics = Toolkit.getToolkit().getFontLoader().getFontMetrics(font);
double length = fontMetrics.computeStringWidth("The text ");
But I guess this is the wrong direction?
But if your font is monospaced you can compute the width of one character and
then just simply divide the width of the textArea by the width of one character and you get the amount of max characters per line.
double widthPerChar = fontMetrics.computeStringWidth("A");
double maxCharsPerLine = textArea.getWidth() / widthPerChar;
I am looking for a function which should take parameters as Font name, sample character, width, height of the sample character and should return Font Size.
It must look like this:
GetFontSize(<Font Name>, <Sample Character>, <Sample Character Width>,
<Sample Character Height>)
which must return the font size,
Is this possible in delphi?
You may want to take a look at this page that discusses font size and points.
It uses the following to convert between the points and pixel size:
Arial 12pt at 96 dpi:
font size in points 12
font size in pixels = ------------------- × 96 dpi = ---- × 96 = 16 pixels
72 points per inch 72
You could use that for your conversion. You just need to be aware of possible differences in your screen dpi as Blorgbeard stated. Points are usually used to describe the size on paper. You need to decide how you want to map that to the screen. For example many programs will allow you to set a zoom level. That does not change the printed size on paper but does affect the pixel height on the screen.
Depending on what you are trying to accomplish you may need to get the actual sizes of the font. If you are trying to find out exactly how the font is put together take a look at Obtaining Font Metrics The code on that page uses the .Net libraries but it has a good explanation. If you want to get the Text Metrics in Delphi you would use the GetTextMetrics function.
As Rob stated in his comment you can draw text at a specific height by setting the Font.Size property to the negative height in pixels. Windows will then draw the text out at that height. In that case you don't need a specific letter or the width as you have in your prototype function. For a given font size each letter will have a different height and width. I.E. capital letters will be taller than lower case letters and letters like "W" will be wider than letters like "i".
I'm only aware of methods to do the opposite - that is, to get pixel sizes from point sizes.
The only way I can think of is to set up a TCanvas, and repeatedly call GetTextExtent on it, changing the font size each time, until you get a size that's acceptably close to what you want.
Depending on how accurate you need this, you could just convert your desired height in pixels to points - a point is 1/72 of an inch, and your screen is probably 96 pixels per inch (but check GetDeviceCaps to get the real figure). See this question.
That would get you a font size pretty close to the pixel size you want.
