Five concrete examples of the CSS Border Radius Generator in real use. Each one shows the situation, what you put in and what comes out, so you can copy the structure, swap in your details and adapt it this week.
Example 1: Rounding cards and profile images
The task: Rounding cards and profile images. You start from corner values in pixels or percentages, set uniformly or per corner.. The tool returns a border-radius property matching your chosen shape., giving you precise rounded or organic corners without counting brackets by hand. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 2: Building organic blob shapes
The task: Building organic blob shapes. You start from corner values in pixels or percentages, set uniformly or per corner.. The tool returns a border-radius property matching your chosen shape., giving you precise rounded or organic corners without counting brackets by hand. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 3: Designing pill-shaped badges
The task: Designing pill-shaped badges. You start from corner values in pixels or percentages, set uniformly or per corner.. The tool returns a border-radius property matching your chosen shape., giving you precise rounded or organic corners without counting brackets by hand. you can edit rather than a blank page.

Example 4: Matching a design system radius scale
The task: Matching a design system radius scale. You start from corner values in pixels or percentages, set uniformly or per corner.. The tool returns a border-radius property matching your chosen shape., giving you precise rounded or organic corners without counting brackets by hand. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 5: Tuning individual corners on a panel
The task: Tuning individual corners on a panel. You start from corner values in pixels or percentages, set uniformly or per corner.. The tool returns a border-radius property matching your chosen shape., giving you precise rounded or organic corners without counting brackets by hand. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
A Full Worked Example
Input: top-left and bottom-right at 40px, other corners at 8px
border-radius: 40px 8px 40px 8px;
The pattern behind every example above: context and constraints go in, structure comes out, and your edit makes it true.
How to Build Your Own Examples
- Take a task already on your calendar for this week.
- Write the brief in two sentences: the job and the audience.
- Generate, compare against the version you would have written manually.
- Save the prompt alongside the result so the second run takes seconds.
Getting More From Each Example
Most people stop at the first result. Generate a second version with one changed variable - length, tone or angle - and compare. The better version usually appears on the second run, not the first.
Frequently Asked Questions
What is the shorthand order?
Values run top-left, top-right, bottom-right, bottom-left - the tool writes them in that order.
Should I use pixels or percentages?
Pixels give fixed corners; percentages scale with the element, which suits circles and pills.
Why does my circle look like an oval?
The element is not square - equal percentage radii on unequal sides always produce an ellipse.
Is my design saved?
No - everything runs in your browser, so copy the code before closing the tab.
