Is Bold 600 or 700? Understanding Font Weight Terminology
When it comes to typography, understanding the font-weight terminology is crucial for both web designers and developers. In CSS, the term "bold" is typically associated with a font-weight value of 700. However, "bold" can sometimes refer to 600 in certain contexts, particularly when using specific fonts that define their own weight scales. This article will explore the nuances of font-weight values, helping you make informed decisions in your design projects.
What Is Font Weight in Typography?
Font weight in typography refers to the thickness or boldness of a character’s strokes. It plays a significant role in the visual hierarchy of text content, influencing readability and emphasis. In CSS, font weights are defined using numerical values ranging from 100 to 900, with each increment representing a different level of boldness.
Common Font Weight Values
- 100: Thin
- 200: Extra Light
- 300: Light
- 400: Normal (Regular)
- 500: Medium
- 600: Semi-Bold
- 700: Bold
- 800: Extra Bold
- 900: Black
Is Bold 600 or 700?
The confusion between whether "bold" is 600 or 700 often arises from the way different fonts interpret these weights. In most standard web fonts, 700 is the default value for bold text. However, some fonts may use 600 as their bold weight, particularly if they offer a broader range of weight variations.
Example: Font Weight Variations
Consider the following example of how different fonts might define bold:
| Font Name | Regular Weight | Semi-Bold Weight | Bold Weight |
|---|---|---|---|
| Arial | 400 | 600 | 700 |
| Roboto | 400 | 500 | 700 |
| Open Sans | 400 | 600 | 700 |
In this table, you can see that while Arial and Open Sans use 700 for bold, Roboto reserves 700 for bold but also offers a medium weight at 500.
Why Does Font Weight Matter?
Understanding font weight is essential for several reasons:
- Readability: Different weights can enhance or hinder readability. Lighter weights are often used for body text, while bolder weights are reserved for headings.
- Aesthetics: Font weight contributes to the overall aesthetic of a design. Choosing the right weight can create a sense of balance and harmony.
- Accessibility: Proper use of font weight ensures that text is accessible to users with visual impairments.
How to Choose the Right Font Weight?
Selecting the appropriate font weight involves considering the context and purpose of your text. Here are some tips:
- Assess Your Audience: Consider the preferences and needs of your target audience. Older readers may prefer heavier weights for better legibility.
- Define the Purpose: Use bold weights for emphasis, such as headings or calls to action, and lighter weights for longer passages of text.
- Test Across Devices: Ensure that your chosen font weights display well across different devices and screen sizes.
Practical Example: Applying Font Weight in CSS
To apply font weight in CSS, you can use the following syntax:
h1 {
font-weight: 700; /* Bold */
}
p {
font-weight: 400; /* Normal */
}
