The width and height attributes in HTML specify the size of an image in pixels. In HTML 4.01, the height could be defined in pixels or in % of the containing element. In HTML5, the value must be in pixels. This wikiHow teaches you how to specify the size of an image in your HTML code.
Steps
-
1Open your HTML document a text editor. Windows and Mac computers come with default text editor programs like Notepad and Text Edit that will work to create or edit HTML.

2Add this line to your script:
<img src="imagefile.jpg" alt="Image" height="42" width="42">
-
src
is the file path to your image. -
alt
is the tag you give for image. - Note that those numbers are in pixels.
- You can also use the
style
tag. For example, you'd have the following code in your text:<img src="imgfile.jpg" alt="Image" style="width:500px;height:600px;">
. Thestyle
tag ensures the image stays that size and overrides any further image size commands.[1]

height
andwidth
numbers. For example, if you enter 21 in thewidth
and 21 in theheight
areas, you'll get an image half the size as the original. -
