Dimensions of Standard Web Design

When designing a website, you need to consider the following dimensions:

1. Fixed layout (standard size)  : The width is set to a specific value. It's a fixed size.

2. Fluid layout (flexible size):  The size is calculated as a percentage. The width of the web page can change according to the browser.

3. Elastic layout:  It's a combination of the two types mentioned above.

Units in website dimensions:

- Pt, pc, cm, mm, in: These are absolute sizes. They don't change when you switch display devices. For example, if you use an Arial font with a size of 10pt, it will display the same size on all devices.

- Px (pixel): This is the unit for one point on the screen. For instance, a full HD resolution screen with 1920 × 1080 pixels would have 2,073,600 pixels, evenly distributed across 1920 columns and 1080 rows.

- %, em, rem: % is the unit for flexible sizes. For example, an image set with a width of 50% will have a width equal to 50% of the display screen. "Em" is a unit similar to % and is used for font sizes, while "rem" is used for the font size of the HTML.

Size of the standard website

Standard website size, also known as fixed layout, refers to the fixed width of the web. The width of the web is usually 800px, 1000px, 960px, or 1260px.

The common fixed size designed by designers is 960px, suitable for display on screens with a resolution of 1024 or higher.

This size is applied to 80% of websites compared to fluid sizes. Fixed Layout ensures the consistency of resolution, controls various display factors, and doesn't disrupt the web code.
