Convention

Jakob's Law

Users spend most of their time on other sites. They prefer your site to work the same way.

  • 1Leverage existing mental models from popular interfaces.
  • 2Don't reinvent standard UI patterns without good reason.
  • 3Place navigation, search, and key actions where users expect them.
  • 4When innovating, bridge familiar and new patterns gradually.

Compare a conventional card layout with an unconventional one. Users intuitively understand the familiar pattern.

The conventional layout follows patterns users know from Amazon, Shopify, and other e-commerce sites.

1// ✅ Good: Conventional e-commerce card layout
2<div className="border rounded-lg overflow-hidden">
3  <img src={product.image} alt={product.name} />
4  <div className="p-4">
5    <h3 className="font-semibold">{product.name}</h3>
6    <p className="text-gray-500 text-sm">{product.description}</p>
7    <div className="flex justify-between items-center mt-3">
8      <span className="font-bold">${product.price}</span>
9      <button className="bg-blue-600 text-white px-4 py-2 rounded">
10        Add to Cart
11      </button>
12    </div>
13  </div>
14</div>

16// ❌ Bad: Unconventional layout that confuses users
17<div className="p-4">
18  <button className="mb-2">Buy</button>
19  <span>{product.price}</span>
20  <img src={product.image} alt="" className="mt-4" />
21  <h3>{product.name}</h3>
22</div>

Follow established conventions. Users shouldn't have to learn your unique patterns.
