High-Fidelity Mockups

In short

Once the structure works, it's time to make it real. High-fidelity mockups apply your colours, type, spacing and real content, so everyone sees exactly what will ship.

Polished, pixel-accurate visual designs applying Phase 2's principles — color, typography, spacing — to a wireframe's structure, representing what the final product should actually look like.

Think of it like this

The sweet shop display

The halwai's display counter shows each mithai exactly as you'll get it: same size, same silver varq, same box. You decide by looking at the real thing. Hi-fi mockups are that display for your app.

Watch it happen

Same screen, two fidelities

Low-fi

Grey boxes and placeholder lines
Tests structure and flow
Minutes to change

High-fi

Real type, colour, images and copy
Tests look, feel and clarity
Ready for handoff and testing

Go hi-fi only after the low-fi flow has been tested. Polish on a broken flow is wasted effort.

The big ideas

What you need to know

Use your styles

Apply saved colour and text styles, not one-off values. It keeps every screen consistent.

Real content

Use realistic names, prices and photos, including long ones, so layouts are tested properly.

All the states

Design loading, empty, error and success states, not just the perfect happy screen.

Real device sizes

Check your mockup on an actual phone. Text that looks fine on a monitor can be tiny in hand.

Save yourself the pain

Common mistakes

Oops

Designing only the happy path in hi-fi.

Do this instead

Include empty, loading and error versions. Developers need them, and users will see them.

Oops

Picking colours and sizes by eye on every screen.

Do this instead

Use your type scale, colour styles and spacing steps from the design system.
