I want to use the following character in a page:
<div>▼</div>
(it's a down arrow character). Is there a way to change its size? I'm not even sure how its initial size is determined anyway - can we apply a font size to it? Or is there some css scale attribute we can apply to it?
Or can I specify its exact width/height in pixels?
Thank you
You can use CSS to control it just like any other text.
https://developer.mozilla.org/en-US/docs/CSS/font-size
The size of the character is determined by the font family and the font size. Both of them can be set as usual in CSS, with the font-family and font-size properties (or even using old-fashioned HTML font tag). Setting font-size different from other text on the same line tends to cause uneven line spacing, but this does not matter if you are using the character in a block of its own, as the div markup suggests.
The character denoted by ▼ is not an arrow but U+25BC BLACK DOWN-POINTING TRIANGLE “▼”. Its relative size (relative to font size) varies a lot by font family, so you should primarily consider the font family choice, using a reasonable list of font families (with comparable size for this character), and only if needed consider font size too.
Just like any other font is controlled
<div style="font-size:x-large">▼</div>
The same way you control the size of any other character. Just set the font size.

I need to create a graphical element that needs to be exactly twice the height of a capitalized letter.
I have the font size defined externally with JS using 'px' and then the graphic is drawn based on this same value.
As a rule of thumb, I have been using 1.5x of the px font-size value to be the capital height. However, this is not accurate enough and changes at larger sizes.
so what exactly does font size define and is there a way to know its mathematical relation to a capitalized letter in a font?
We have a number of divs on a page containing text. The text is explicitly set to a certain font-size via CSS. In some circumstances the font-size is increasing without our intervention. It seems to be related to the length of the text in the DIVs. i.e. once it gets to a particular size adding a character increases the font-size, removing it again reduces the font-size.
We haven't got any fancy libraries included to scale the font.
In chrome dev tools it shows the variation in the font set via CSS, and then the computed size here:
Why does the font go from 16px to 19.555555px? What are we missing?
thanks!
The little web application I am writing populates a temporary invisible container with some text, measures the resulting height, and then uses it to generate some guis based on that height.
This is done because, not all fonts are mon-spaced and as such need to be measured each time to determine how much space they will take up.
Now, I may need to scale the entire UI to fit a different screen size and was wondering if I can just scale the resulting height reliably.
Simply Put: Are all front glyphs guaranteed to be proportionate when scaled or can you have different glyph widths/spacing at different font sizes?
e.g. Will a font set at size 20 always be exactly 2 times the size of a font set at size 10?
EDIT: Here is another view of the test I did and posted in the comments below:
When you double font size, it is doubled exactly. But this does not mean that glyphs are scaled proportionally. The font size is simply a property of the font, not a property of glyphs. Glyphs are scaled, but the results are not and cannot be exact, due to the granularity of rendering: the abstract glyph shapes must be rasterized, i.e. converted to pixel maps, and this inevitably changes their shapes.
For example, consider the horizontal stroke of the letter “e”. The width depends on the font size, of course, but in rasterization, it needs to be mapped to one pixel, two pixels, or some other number of pixels. Even subpixel rendering does not change this; it just modifies the way rasterization works. Thus, the width of the stroke as rendered on screen (or paper) cannot exactly reflect the font size. And different strokes in a glyph will behave differently, so that an increase of font size does not mean exact magnification of a glyph.
I just want to know the how many "px" occupy the single " ". so that i can calculate and give the padding instead of  
It's not possible to know this accurately, because it will depend on the font's metrics and the way it's rendered. A non-breaking space is usually rendered with the same width as a regular space in the same font, it just suggests to the browser not to wrap at that point or collapse the space.
You should never rely on fonts rendering a particular way in order to line up design elements on the page. Specify distances in units that are appropriate, and don't use non-breaking spaces in situations for which they aren't suitable.
You could start with a value of, say, around 0.4em. But if you absolutely have to exactly match the width of a non-breaking space, you are using a non-breaking space incorrectly.
Depends on the font and its size. See this fiddle:

It completely depends on the font and font size you are using: http://jsfiddle.net/nivas/CV5mQ/
Today (2022) you can use the CSS ch unit - which is supposed to represent the width of one "character" of the current font. Some implementations have 1 ch be equal to the width of the space character, some of them have it to be equal to the width of the 0 character.
This is generally, roughly equal to ~60% of the font-size - but it can be completely different on certain (non monospace) fonts.
It depends on the font size. Even you can calculate it on Photoshop.
In html:
<p>How are you? &nbps; what are you doing?</p>
copy this from browser and paste it in photoshop:
it will look like this:
How are you? what are you doing?
Then zoom it and check the px.
If you want.
How can we increase the font size in html?
<font face="Garamond" size="7">
up to this size only it is working.
Is there any way to increase the size of the font?
You can use the font-size css property: Example
<span style="font-size:20px;">This is large Text...</span>
There is also <font> tag but it is deprecated.
The largest size the font tag supports is 7. If you need it to be larger, you will have to use CSS, which you should probably be using anyway because the font element is deprecated.
The CSS font-size values, xx-small, x-small, small, medium, large, x-large, and xx-large are comparable to <font size="1"> through <font size="7"> if you want to specify the size like that, but you would run into the same size limitation. The more typical way is to use px or pt for absolute sizes, and % or em for relative sizes.
Adding onto the answers that exist. Inline styling is usually frowned upon, because:
In huge HTML pages, this can cause a maintenance nightmare for anyone that has to maintain it.
Does not separate content from design.
They add unnecessary length to the HTML page.
