Quick answer: Flat design strips away shadows, gradients, bevels and textures in favour of simple shapes, solid colours and clear type. It suits most business websites because it looks tidy, scales well on phones and keeps pages light. The risk is that buttons, links and form fields can stop looking clickable. If you go flat, keep enough visual cues (contrast, a little depth on buttons, underlined or clearly coloured links) that visitors always know what they can tap.
Over the last few years, the look of the web has changed a lot. Microsoft’s tile style in Windows 8, Apple’s redesign of iOS 7 and Google’s Material Design guidelines all pushed away from glossy buttons and leather textures towards plainer, flatter interfaces. Many business owners now look at their own site, still full of drop shadows and shiny icons, and wonder whether it looks dated. Often it does. But a redesign purely to follow a style can do more harm than good if it makes the site harder to use.
What flat design means
The older style, often called skeuomorphism, tried to make screen elements look like real objects: notepads with paper texture, buttons that looked raised and pressed, calendars with stitched leather. Flat design does the opposite. It treats the screen as a screen.
Typical features include:
- Solid colours rather than gradients and glossy highlights.
- Simple icons made of basic shapes and lines.
- Strong typography doing most of the work of hierarchy.
- Plenty of white space around content.
- Grid based layouts that rearrange cleanly on smaller screens.
- Minimal decoration, so the content stands out.
A softer version, sometimes called flat 2.0 or almost flat, adds back a little depth: subtle shadows under cards and buttons, layers that sit above one another, small amounts of motion. Material Design is a good example of this middle ground.
Why flat design became popular
It works well on phones
Simple shapes and solid colours look sharp on high resolution screens and scale to any size. Responsive layouts are easier to build when you are not relying on large background images and sliced graphics.
Pages are lighter
Fewer image based effects means fewer files to download. Many visual details can be drawn with CSS instead of images, which helps page speed, especially on mobile connections.
Content comes first
With less decoration competing for attention, headings, product photos and calls to action can stand out more clearly. When it is done well, flat design makes a page easier to scan.
It looks current
Rightly or wrongly, visitors judge credibility partly on appearance. A site that looks like it was built many years ago can make people wonder whether the business is still active.
Where flat design causes problems
Buttons that do not look like buttons
This is the biggest issue. When a button is just a coloured rectangle with text, or worse, outlined text on a photo (the so called ghost button), some visitors do not realise it is clickable. On a desktop they may hover and find out. On a phone there is no hover, so they simply do not tap.
Links that blend into text
Flat sites often remove underlines from links and rely on colour alone. If the link colour is close to the text colour, or if a visitor has trouble telling colours apart, links disappear.
Form fields with no edges
Some flat designs show form fields as a single line or a faint box. People can miss fields entirely, or not see where to click to start typing.
Low contrast
Light grey text on white looks elegant in a mockup and is hard to read on a phone in daylight. Pale colour palettes are a common side effect of chasing a minimal look.
Everything looks the same
When every element is a flat coloured block, it can be hard to tell headings from buttons from decorative boxes. Hierarchy has to come from size, spacing and colour, and that takes more care than adding a shadow.
How to use flat design without hurting conversions
Keep clickable things obvious
Give primary buttons a solid fill in a colour that is used for nothing else on the page. A small shadow or a slightly darker bottom edge helps them read as buttons. Change the colour on hover and when tapped so people get feedback.
Underline links in body text
Underlines in paragraphs are the clearest signal there is. You can drop them in navigation menus, where people expect every item to be a link, but keep them in content.
Give form fields a clear outline
A visible border on all sides, a label above each field and a clear focus state when someone clicks in will reduce mistakes and abandoned forms.
Check contrast
Body text should be dark enough to read comfortably on a phone. The WCAG 2.0 guidelines recommend a contrast ratio of at least 4.5 to 1 for normal text, and free contrast checkers will tell you whether your colours meet it.
Use one accent colour for actions
If your main call to action colour is also used for headings, icons and backgrounds, it stops meaning anything. Reserve it for the things you want people to click.
Let hierarchy come from type and spacing
Large, clear headings, generous spacing between sections and consistent sizes for similar elements give a flat page structure without needing decoration.
Is flat design right for your business?
Probably yes if
- Your site looks dated and you are planning a redesign anyway.
- A large share of your visitors are on phones.
- Your content and photography are strong enough to carry the page.
- You want a site that is easy to update and keep consistent.
Be careful if
- Your audience includes many older or less confident web users who rely on familiar cues.
- Your site is built around complex forms, booking tools or a checkout.
- Your designer’s mockups look beautiful but you struggle to tell what is clickable.
In practice, most businesses end up with something in between: a clean, mostly flat look with just enough depth on buttons and form fields to keep them obvious.
Test it rather than guess
Design debates are easy to have and hard to settle by opinion. If you are changing button styles or layouts on pages that bring in enquiries or sales, test the change. Even a simple test of a flatter button against your current one can tell you whether visitors notice it. Our guide to A/B testing explains how to run one properly, and the landing page optimisation guide covers what else to look at on key pages.
You can also do quick checks without any tools:
- The five second test. Show someone a page for five seconds and ask what they could click. If they miss your main button, it is not clear enough.
- The squint test. Squint at the page or blur a screenshot. The most important actions should still stand out.
- The phone test. Hand your phone to someone who has not seen the site and ask them to send an enquiry. Watch where they hesitate.
FAQ
Is flat design better for SEO?
Not directly. It can help indirectly through lighter pages and a better mobile layout, but search engines care about content, speed and usability, not visual style.
Are ghost buttons a bad idea?
They are fine for secondary actions. For your main call to action, a solid button is usually clearer.
Do I need a full redesign to go flatter?
Not always. Updating colours, typography, icons and button styles can modernise a site a great deal without rebuilding every page.
