The most common mistake is fitting into one slide what belongs in several. If a slide starts to feel crowded, split it. Think of it as a meal: you do not eat it all at once.

The fewer elements on a page, the easier they are to arrange. A slide with many elements is hard even for a professional designer, because every relationship between them has to be balanced.

Cutting the non-essential and splitting large blocks of data across slides gets you clean, readable pages without needing any design skill.

Cut, cut, cut. Removing everything not absolutely necessary is the key designer skill — long sentences, long headers, every element that is not earning its place.

Separation is the basic principle of order. In graphic design we separate with space, and also by size, colour and distinctive features — but space matters most. A clean presentation always has a lot of it. Space is what lets a slide breathe and gives the eye somewhere to rest.

When a slide carries many elements, avoid chaos by grouping them into two or three distinct clusters. Space between groups is larger than space within them.

This tricks the brain into seeing less complexity: first a few large shapes, then detail inside each one.

Size creates hierarchy, and hierarchy is readability. Usually one element is the composition centre — a large header or a large visual — and it tells the eye where to start.

Two or three elements at the same large size create a conflict: the brain cannot tell which to read first. The less important the message, the smaller it should be.

Consistent fonts, colours and sizes are what make a deck look organised — and it applies to structure as much as styling.

Think of each slide as a layout module. A deck has a limited set of modules that repeat and vary, each handling a different amount of information.

A layout grid keeps spacing consistent across every slide, and gives the layout modules something to sit on.

For type, contrast means combining large and bold with small and light. The most common typographic mistake is too little difference between sizes — which reads as monotony. Expect at least three distinct sizes: headers, body, captions.

For layout, contrast means not repeating the same module twice in a row. Every slide on the same white background can work, but usually you want variation: a dark slide after a light one, a simple slide after a dense one.

Prefer visuals built around a single large element. If a header has to sit on the image, the image needs room for it — an out-of-focus area, or a flat homogeneous texture.

The most engaging images often carry the message by association rather than directly. If your work is sensitive or the process is complex, a literal image may not exist — and choosing the alternative is part of identity work, so ask us.

To lay small text over a picture, drop its brightness, contrast and opacity substantially so the text stays readable. Backgrounds are what keep a deck from feeling monotonous.

The shorter the header, the larger it can be. Before accepting a long one, ask whether the same thing can be said in fewer, simpler words.
