Website Font Weight Guide
Need to know whether website text is regular, medium, semibold, or bold? This guide shows the simple hover-to-inspect workflow to check font weight without reading CSS.
Quick Answer
- Install FontFinder and open the webpage text you want to inspect.
- Activate the extension and hover over the exact text element.
- Read the numeric font weight, such as 400, 500, 600, or 700.
- Save weight with font family, size, line-height, and color so the typography note is actually useful.
Regular
Usually used for body text, paragraphs, descriptions, and readable long-form copy.
SemiBold
Often used for section headings, labels, nav items, and medium-emphasis UI text.
Bold
Common for hero headlines, strong CTAs, important numbers, and high-priority text.
Font weight controls how thick or light text appears on a webpage. It decides whether a headline feels strong, a label feels clickable, or a paragraph feels calm and readable.
The confusing part: “bold” is not always just bold. CSS can use keyword values like normal and bold, numeric values like 400 and 700, or variable font ranges like 100–900. FontFinder makes this easier by showing the computed weight directly from the live webpage.

Font weight changes hierarchy. A 700-weight headline attracts attention. A 400-weight paragraph feels easier to read. A 500 or 600-weight navigation label can look more clickable without becoming too heavy.
| Text Role | Common Weight | Why It Works |
|---|---|---|
| Body paragraph | 400 | Readable for longer text blocks. |
| Navigation label | 500–600 | Clear without overpowering the page. |
| Hero heading | 600–800 | Creates strong visual hierarchy. |
| Button text | 600–700 | Makes the action feel clear and confident. |
Pro Design Tip: Font weight should be judged with font size and color. A 700-weight 14px label may feel smaller than a 500-weight 24px heading because size changes perceived strength.
Prerequisites: What You Need
You do not need to read CSS manually. You only need a live webpage, a Chromium-based browser, and the FontFinder hover-to-inspect workflow.
A live webpage
Open the page where the text weight is actually rendered.
Chrome or Chromium browser
Chrome, Edge, Brave, Opera, and Vivaldi are common choices.
FontFinder installed
Pin it to the toolbar for quick typography inspection.
How to Check Font Weight on a Website Without Reading CSS
1Install FontFinder
Add FontFinder to your browser and pin it to the toolbar. This gives you a quick font weight checker without opening DevTools.
2Open the webpage
Go to the page where the text appears. Wait for the page to fully load because some fonts and weights load after the first visual render.
3Activate FontFinder
Click the FontFinder icon. The extension is now ready to inspect headings, paragraphs, buttons, links, pricing cards, and labels.
4Hover over the exact text
Move your cursor over the text you want to inspect. If you only need a deeper font-weight guide, use FontFinder’s guide to finding font weight on any website.
5Copy the numeric weight
Save the weight value with font family, size, line-height, and color. A useful note looks like this: Inter · 700 · 52px · 60px line-height · #111827.
Quick Type Tweak: If text looks bold but FontFinder shows 500 or 600, the font design itself may have thick strokes. Visual weight and CSS weight can feel different.
Real FontFinder Workflow Example
Imagine you are reviewing a SaaS homepage. The hero headline looks bold, the navigation feels medium, and the paragraph looks regular. You want exact values for a design audit.
| Text Element | FontFinder Output | Design Meaning |
|---|---|---|
| Hero headline | Inter · 52px · 700 · #111827 | Bold hierarchy for primary attention. |
| Navigation item | Inter · 15px · 500 · #374151 | Readable, clickable, but not too heavy. |
| Body paragraph | Inter · 18px · 400 · #4b5563 | Comfortable reading weight for longer copy. |
What Font Weight Values Mean
| CSS Weight | Common Name | Typical Use |
|---|---|---|
| 100–300 | Thin / Light | Large display text, luxury/editorial styling, low-emphasis UI. |
| 400 | Regular / Normal | Paragraphs, descriptions, readable body copy. |
| 500 | Medium | Navigation, tabs, labels, secondary headings. |
| 600 | SemiBold | Subheadings, cards, UI labels, important text. |
| 700–900 | Bold / ExtraBold / Black | Hero headings, CTA emphasis, price numbers, strong alerts. |

Font Licensing Caution: Identifying a font weight does not mean you can use that font commercially. Check whether the typeface license allows the exact weight you want to use in websites, apps, ads, or client projects.
Why Visual Weight Can Differ from CSS Weight
| Reason | What Happens | What to Check |
|---|---|---|
| Different font design | One font’s 500 can look like another font’s 600. | Compare family + weight together. |
| Large font size | Big text can feel heavier even at lower weights. | Check size and line-height. |
| Dark color | Dark text can look bolder than lighter gray text. | Check font color too. |
For a better design decision, weight should be reviewed with font choice and loading behavior. These guides on choosing fonts for a website and font loading strategies can help when you move from inspection to implementation.

Mistake 1: Calling everything bold
Wrong: “This text is bold.”
Correct: “This text uses font-weight: 700 with 52px size and #111827 color.”
Mistake 2: Ignoring variable fonts
Wrong: Assuming a font only has 400 and 700.
Correct: Check whether the font supports a broader range like 100–900.
Mistake 3: Copying weight without context
Wrong: Copy weight 700 and use it everywhere.
Correct: Use different weights for headings, labels, buttons, and body text.
Font Weight Inspection Checklist
✅ Inspect the exact text element, not the full page.
✅ Save numeric weight, such as 400, 500, 600, or 700.
✅ Record font family with the weight value.
✅ Check font size and color because both change perceived weight.
✅ Compare heading, body, button, nav, and caption weights separately.
✅ Confirm the font license before using the same font weight commercially.
FAQ: Checking Font Weight on a Website
How do I check font weight on a website?
Use FontFinder, activate it on the webpage, and hover over the text. The panel shows the computed font weight along with font family, size, line-height, and color.
