HTML Font Size Codes

Here’s a rundown on all the various HTML font size codes you can use to make text bigger or smaller on your web pages.

First of all, you can designate the text size on your web page using the ‘size’ attribute in the HTML font element code. If no size is defined for text on a web page then the web browser will display the text at size 3.

The value that you enter for the size attribute is a number representing any one of seven different relative sizes. These number 1 through 7 respectively. These are the results you will get when specifying the size attribute:

. into your tag where font size equals any number from 1 to 7.

Your visible text goes here and will look like this.

Alternatives

Another way of designating your text size is to enter a number from 1 through 4 which either adds or subtracts from your basefont size. In the absence of a basefont declaration, the default basefont is size 3. By entering a value of «+1» for the size attribute you designate your text to be displayed one size bigger which then equates to size 4. Likewise a value of «+2» equates to font size 5. Going in the other direction, a value of «-1» equates to size 2 and «-2» equates to size 1 (basefont size 3 — 2 = font size 1).

Many WSYIWYG editors produce source code using this system of font sizing. This should help explain things if you ever decided to take a peek at the source code while using a WYSIWYG editor and subsequently wondered what all that «+2» and «-1» stuff was about.

Still another way of defining your text size on a web page is to use the big and small font style elements. This system works very similar to the size=±1 system in that using one set of . tags equates to one size bigger while using one set of . tags equates to one size smaller.

Hence, if you were starting from a blank web page with no formatting applied yet (default basefont size 3), the following three examples will produce identical results:

Nesting a pair of . tags one within the other and using this to format text has the same effect as rendering the text two sizes bigger or, in effect, using the size=»+2″ attribute-value pair with the font element.

Hence, the following three examples will produce identical results:

Three of a kind all over again.

Three of a kind all over again.

Three of a kind all over again.

Many WYSIWYG editors use this big/small font sizing system as well. This is one of the drawbacks of using these ‘instant cakemix’ web authoring programs. They can at times produce some very bloated and messy source code. Using one of these programs, when the user highlights the text he wants to make really big and then clicks four times on the make-text-bigger button (quite often denoted by an a+ button on the user interface), the resulting source code will look like this:

This is rendered much easier by simply putting:

An even more ridiculous scenario is produced when the WYSIWYG user highlights some text he would like to make bigger and then, for example, clicks three times on the make-text-bigger button but then later changes his mind and decides some previously typed text would be better at the original size. So then —often unaware of what he is really creating behind the scenes in the source code— he goes back, highlights that text and clicks three times on the make-text-smaller button producing a bunch of source code that is a complete waste of space:

No sizing will be applied to this text.. . while this text will appear at size 6.

This is exactly the same as simply putting:

No sizing will be applied to this text. . while this text will appear at size 6.

Once you’ve tried to debug a web page stuffed to the gills with this kind of useless source code á la etcetera, ad nauseum, you may give some second thoughts as to how «easy» some WYSIWYG editors really are.

So what size text should you use? This is partly a matter of taste and partly a matter of necessity and can also depend on what font style you use.

Text that is too small can be difficult and sometimes even impossible to read (Arial size=»1″).

On the other hand, text that is too big can have the effect of ‘shouting’. This can turn viewers away from your web page, especially if the whole page is filled with text like this (Arial size=»6″).

Most web page authors tend to hang around the size 3 — size 5 range for normal reading purposes (depending on the font style) but may increase the font size for headers and titles.

CSS Font Size

Being able to manage the text size is important in web design. However, you should not use font size adjustments to make paragraphs look like headings, or headings look like paragraphs.

Always use the proper HTML tags, like — for headings and

for paragraphs.

The font-size value can be an absolute, or relative size.

• Sets the text to a specified size
• Does not allow a user to change the text size in all browsers (bad for accessibility reasons)
• Absolute size is useful when the physical size of the output is known

• Sets the size relative to surrounding elements
• Allows a user to change the text size in browsers

Note: If you do not specify a font size, the default size for normal text, like paragraphs, is 16px (16px=1em).

Set Font Size With Pixels

Setting the text size with pixels gives you full control over the text size:

Example

Tip: If you use pixels, you can still use the zoom tool to resize the entire page.

Set Font Size With Em

To allow users to resize the text (in the browser menu), many developers use em instead of pixels.

1em is equal to the current font size. The default text size in browsers is 16px. So, the default size of 1em is 16px.

The size can be calculated from pixels to em using this formula: pixels/16=em

Example

h2 font-size: 1.875em; /* 30px/16=1.875em */
>

p font-size: 0.875em; /* 14px/16=0.875em */
>

In the example above, the text size in em is the same as the previous example in pixels. However, with the em size, it is possible to adjust the text size in all browsers.

Unfortunately, there is still a problem with older versions of Internet Explorer. The text becomes larger than it should when made larger, and smaller than it should when made smaller.

Use a Combination of Percent and Em

The solution that works in all browsers, is to set a default font-size in percent for the element:

Example

Our code now works great! It shows the same text size in all browsers, and allows all browsers to zoom or resize the text!

Responsive Font Size

The text size can be set with a vw unit, which means the «viewport width».

That way the text size will follow the size of the browser window:

Hello World

Resize the browser window to see how the font size scales.

Example

Hello World

Viewport is the browser window size. 1vw = 1% of viewport width. If the viewport is 50cm wide, 1vw is 0.5cm.

font-size

Определяет размер шрифта элемента. Размер может быть установлен несколькими способами. Набор констант ( xx-small , x-small , small , medium , large , x-large , xx-large ) задает размер, который называется абсолютным. По правде говоря, они не совсем абсолютны, поскольку зависят от настроек браузера и операционной системы.

Другой набор констант ( larger , smaller ) устанавливает относительные размеры шрифта. Поскольку размер унаследован от родительского элемента, эти относительные размеры применяются к родительскому элементу, чтобы определить размер шрифта текущего элемента.

В конечном итоге, размер шрифта сильно зависит от значения свойства font-size у родителя элемента.

Сам размер шрифта определяется как высота от базовой линии до верхней границы кегельной площадки, как показано на рис. 1.

Синтаксис

font-size: абсолютный размер | относительный размер | значение | проценты | inherit

Значения

Для задания абсолютного размера используются следующие значения: xx-small , x-small , small , medium , large , x-large , xx-large . Их соответствие с размером шрифта в HTML приведено в табл. 1.

Табл. 1. Размер шрифта в CSS и HTML

CSS	xx-small	x-small	small	medium	large	x-large	xx-large
HTML	1	2	3	4	5	6	7

Относительный размер шрифта задается значениями larger и smaller .

Также разрешается использовать любые допустимые единицы CSS: em (высота шрифта элемента), ex (высота символа х), пункты ( pt ), пикселы ( px ), проценты ( % ) и др. За 100% берется размер шрифта родительского элемента. Отрицательные значения не допускаются.

inherit Наследует значение родителя.

HTML Font Size – How to Change Text Size Using Inline CSS Style

Kolade Chris

In HTML, the font you choose will play a major role in the look and feel of your web pages.

You get to pick the font’s color, weight, size, and so on. And all these features make your websites and apps look better and more presentable to the user.

With the font-size property in CSS, you can change how big or small the text is on the web page. You can use this property in any type of CSS you are writing – external, internal, or inline.

In this article, I will show you how to change the size of the text with the font-size property in inline CSS.

What is inline CSS?

Inline CSS is one of the three different ways you can use to style any HTML element.

Instead of targeting the element with a class or id attribute, or the element itself as the selector and styling it with that, you put all the CSS styles in the opening tag.

In addition, you have to make sure all the properties and values of your stylings are inside the style attribute. This style attribute is one of the numerous attributes accepted by all HTML tags.

In the example below, I change the background color of the text to crimson, the text color to #f1f1f1 (light-grey), and the font-weight to bold with inline CSS.

By the way, my browser is zoomed-in to a level of 400% which is why everything appears so big. I didn’t apply any additional styles to accomplish that 🙂

How to Change Text Size Using Inline CSS

To change the size of your text with inline CSS, you have to do it with the style attribute. You type in the font-size property, and then assign it a value.

There are built-in values such as large , larger , medium , small , x-large , and so on:

In the code snippet below, I change the size of the “Hello Campers…” text to x-large, one of the built-in values of the font-size property.

You can also set the value of the font-size property using a number with any unit such as pixels (px), rem, or em.

It’s better to go with numbered values because they give you more freedom to pick any font size you want.

In the code snippet below, I changed the size of the text to 30px with inline CSS:

Conclusion

In this article, you learned how to change text size with inline CSS and the font-size property. You also saw how you can assign values to the font-size property.

Just a heads up, though: inline CSS is great for styling, but you should not rely heavily on it as it makes your HTML hard to read, especially if you are working in a team. You don’t want to be the only one who will be able to read your own code.

Be aware that it also overrides any styling set with internal or external styling. You should use external style or internal style instead, as they make your HTML and CSS codes separate, which is better for readability.

While assigning values to the font-size property, it is better to assign the values in rem units instead of px , for example. This is because when you use rem , the browser will be able to make font size adjustments as the user zooms in or out, which won’t happen when you use px .

Thank you for reading, and keep coding.
