On this page
A quote for a website lands, and the first line says web design. Underneath it are five or six more lines, and it is not obvious where the first one stops and the rest of them start.
So, what is web design. It is the set of decisions about what a site is for, what a visitor meets first, how they move through it and how it holds together on a phone, with how it looks arriving last rather than first.
This post sets out what those decisions are, where design stops and development starts, what you have to supply before any of it can begin, and how you check afterwards whether the thing works. If you would rather talk to somebody who does this for small businesses, that conversation keeps.
What web design settles
Five decisions, taken roughly in that order, and only the fifth is about appearance. What the page is for comes first, because a page with two jobs usually does neither.
Then what a visitor meets first, then how they get from that to the thing they actually came for. Then how the whole arrangement holds when the screen is 375 pixels wide, which is most of the time.
Put like that, appearance is an output rather than the brief. Colour, type and spacing are how the first four decisions get expressed, and they read as arbitrary when the four underneath them were never taken.
This is also why two designs of the same business can be equally handsome and only one of them work. They answered different questions before they answered the visible one.
What does a web designer do
Day to day, a web designer settles those five decisions and draws the result. That means the page structure, the order things appear in, the navigation, the states a form goes through, and the type and colour that carry all of it.
What a web designer does not usually do is write your words, take your photographs or run your business. Those arrive from your side, and the section below is about what happens when they do not.
Web design vs web development, and where content sits
Three separate jobs sit behind one word on an invoice. Design decides how the thing is arranged, development makes it work, and content is the words and pictures that fill it.
The confusion is worth clearing up before you compare two quotes, because a figure that covers one of the three is not comparable with a figure that covers all of them.
| The job | What it settles | What it leaves to the others |
|---|---|---|
| Design | Structure, order, navigation, how it holds on a phone | Whether any of it functions |
| Development | Pages, forms, payments, speed, hosting | Whether any of it reads well |
| Content | The words, the pictures, the offer | Where any of it goes |
A quote that names only one of the three is not cheaper. It is smaller.
The money follows the same split. What design on its own comes to and what the build behind it comes to are separate questions with separate answers, and each has its own post rather than a paragraph here.
If the budget is genuinely small, the useful move is to shrink the site rather than the standard. Where the corners can honestly be cut is a different conversation from what design is.
What you need to supply before design starts
Design cannot start on an empty page in the other sense. Somebody has to say what the business sells, in a sentence, and who is meant to be reading.
Then the words, or at least the substance of them, and the pictures. A layout drawn around placeholder text fits the placeholder, and real copy is always a different length.
The brand is the fourth item, and the one people skip. If there is already a settled view of how the business looks and sounds, design starts from it; if there is not, that gets decided during the project by whoever is drawing.
None of this is a formality. The parts a buyer cannot see are the parts most often quietly left out, and they surface months later.
The website I paid for was looking good but behind the scenes of it it was seriously lacking. It didn't support accessibility, seo, compliance etc - why? Because you have to pay extra for that. I spent a good few weekends and evenings going through it and changing it.

That is the boundary problem stated by somebody who paid for it. Accessibility and search were treated as extras rather than as part of designing a page, and she did the remediation herself.
So ask which of them are inside the fee before anybody starts drawing. It is a cheap question in week one and an expensive one in month six.
What makes good web design, and how you check it
The checks are duller than the arguments. It holds on a phone, it loads, a stranger can find the thing they came for, and somebody using a keyboard or a screen reader can get through it.
The phone one has a measurable floor. HTTP Archive's 2025 Web Almanac reports that the median percentage of pages with meta viewport tags is 93.1% for desktop sites and 95.2% for mobile sites, which is the single tag telling a phone not to render a page as though it were a desktop.
How to check it without a specialist
Accessibility has a published standard rather than an opinion. The W3C's Web Content Accessibility Guidelines set out testable success criteria for contrast, keyboard operation and text alternatives, and they are what an audit is measured against.
The last check is the one only you can do. Hand the site to somebody who has never seen it, name a thing on it, and watch how long they take.
Why the floor has quietly risen
There is a lot riding on the answer. Ofcom reports that UK adults now spend an average of four and a half hours online a day, and almost none of that attention is patient.
Having a site at all is no longer the differentiator either. The government's business survey found 78% of UK businesses said they have a website in 2025 to 2026, against 68% in 2023 to 2024, with micro businesses at 84% and sole traders at 76%.
If you are not sure which of the four checks your current site fails, it is worth having somebody look at it before commissioning a replacement. Quite often the answer is a fix rather than a rebuild.
A website is also one channel among several, and design cannot carry the others. Where a site sits among the rest of the work is worth knowing before the whole budget goes into one page.
The short version is the second line of this post. Web design is four decisions and then a look, and a quote that only prices the look is quoting the smallest part of it.
