A hill is generally a smaller, gentler rise in land, while a mountain is taller, steeper, and more dramatic in shape. There is no single universal cutoff, but many sources use rough height guidelines such as around 600 m / 2,000 ft for mountains, and emphasize that slope and local convention matter too.

What matters most

The biggest difference is usually how people describe the landform: mountains are taller and steeper, while hills are lower and more rounded. In practice, the line can be blurry, because different countries and traditions use different standards. That means one place’s “hill” can be another place’s “mountain”.

Simple rule of thumb

  • Hill: smaller, softer-looking rise in land.
  • Mountain: larger, steeper rise in land.
  • Best shortcut: if it looks tall, rugged, and steep, people usually call it a mountain.

Why the boundary is fuzzy

There is not one global authority that draws the line the same way everywhere. Some definitions focus on elevation, others on slope, and some are just local tradition. So the difference is partly scientific and partly linguistic.

In one sentence: a mountain is usually a taller, steeper landform, while a hill is usually smaller and gentler, but the exact cutoff depends on where you are.
