Font size is measured in points. 1 point = 1/72 of an inch. 12 point font is 12/72 inches high. 72-point font is 1 inch high.
Characters Per Inch
Points are an old unit of measurements. They are the smallest measurement in the typographic system of measure. On a modern system, a point is 1/72nd of an inch (or around 0.357 mm.) On the screen, this gets a little murky. Inches are hard to translate to the resolution of a computer screen, and so points are kept mainly in an effort to make people used to the measurement system comfortable. Originally, a font-size was measured from the top to the bottom of the metal backing on the printer's letter. Now, fonts are normally measured from the top of their ascenders (like the top of a "k") to the bottom of the descenders (like the bottom of a "j".) A 12pt. font is a font that can be measured at 12pts, or a little less than 3/16ths of an inch.
1 typographer's point is equal to 1/72ths of an inch. So 10 points is 10/72ths or 0.138 inches, or a slightly more than 1/8th inches.
The answer is: it depends. It depends on the specific units used. In most Word Processing fonts are measured in units called "points." A point is a very old measurement that involves a very old typsetting tool. It has varied over time. But in the 1990s, a technology called PostScript set the new standard: there are 72 points in an inch. That means that a single point is 1/72nd of an inch, or ~0.353 millimeters. In the world of computing, this still varies some, as inches in print don't really translate well onto screen real estate. To set a font to 72 points using CSS you use the following rule .selector { font-size:72pt;} The other very common unit is pixels. A pixel is a tiny square that lights up on your computer screen. When you put these tiny dots together, they form a picture (your eye does the blending.) 72 pixels is about 4 times the size of the font your question is in at the top of the page. (That's 20px.) The symbol for pixels is px, so the above rule would be .selector {font-size:72px;} Pixels are a digital measurement. Points are a print measurement. There's very little continuity between the two. Other measurements are relative. For instance "em" is the size of one "m" (horizontally) in the font you're currently using. If you're using a bigger font, then 1em is bigger. "ex" is the size of one "x." You can also use percentages "%" 50% is half the size of the current size. 150% is one and a half times the size. The other one is the pica, which is a print unit, that is 12 points. So, like I said at the beginning: it depends. :)
Font size is usually measured in points; 1 inch is approximately 72 points.
It depends on how your computer is set up. Typically for word processing, the font size is generally set at 72pt as 1 inch on the screen, or in non-word processing usage (such as image editing or elsewhere that works on a screen) the default resolution is 96dpi (dots per inch). For printers, check with the documentation for specific quality settings (some can have 600dpi for low resolution and some can go up to at least 2400dpi for high quality).
Font sizes are usually measured in 'points'. 72 point text is text that is the equivalent of 1 inch in height overall. 12 point text is 1/6th of an inch high.
Points in a document refer to the size of the font. One point is approximately equal to 1/72 inch. So, 72 points would be about one inch tall text.
Font size is measured in points. 1 point = 1/72 of an inch. 12 point font is 12/72 inches high. 72-point font is 1 inch high.
A single point is equal to 1/72 of an inch in font size.
The size of the font used in a document is called font size. It is typically measured in points, with one point equal to 1/72 of an inch. Common font sizes range from 8 to 72 points.
Font Size is measured in a system called "points" that are 1/72 of an Inch
There are 72 points per inch. So 1 point would be 1/72 of an inch or 0.0139 inches.
A font is a style of typeface such as Helvetica or Courier. Points describe the size of the font. The definition has changed but usually there are 72 points to the inch. This distance is often used to measure the approximate height of the font with room to spare. Typically the vertical distance from the top of a capital G to the bottom of a lower case g plus a small gap.
12 points type. Note that spacing should be double and margins 1 inch all sides.
Font size is by fractions of 72 of an inch. For example, if a font is 14 pt., then it is 14/72 of an inch, or 7/36. A font size of 72 would be a full inch tall.
