A logo is a small piece of design that does a lot of work. It appears on app icons, websites, invoices, merchandise and social avatars, often at tiny sizes and in less-than-ideal conditions. A good logo is not necessarily the most elaborate. It is the one that is recognised quickly, remembered easily and works everywhere you need it.
The five qualities of an effective logo
Designers often judge a logo against a short list of principles.
- Simple: easy to recognise and reproduce. Fewer shapes and colours usually age better.
- Memorable: distinctive enough to stick after a quick glance.
- Timeless: avoids fleeting trends that will look dated in a couple of years.
- Versatile: works in colour and one colour, large and small, on light and dark backgrounds.
- Appropriate: suits the audience, industry and personality of the brand.
If a logo fails the small-size test, it needs work. Shrink it to the size of a browser tab or app icon. Can you still tell what it is?
Common logo types
| Type | Description | Example idea |
|---|---|---|
| Wordmark | The name set in distinctive lettering | Works best for short, unique names |
| Lettermark | Initials or a monogram | Suits long names |
| Symbol / icon | A standalone graphic mark | Needs strong recognition over time |
| Combination mark | Symbol plus wordmark | Flexible, can be used separately |
| Emblem | Text inside a badge or crest | Traditional, harder at small sizes |
| Abstract mark | Non-literal geometric shape | Distinctive but needs meaning to be added by the brand |
Most modern digital brands choose a wordmark or a combination mark, with a compact version of the symbol for icons.
A practical design process
1. Start with a brief
Write down who the brand is for, what it stands for, three adjectives that describe its personality and where the logo will appear. Our brand identity guide covers the strategy behind this.
2. Research
Look at competitors and the wider industry. Note common colours, shapes and clichés so you can avoid blending in.
3. Sketch widely
Draw dozens of rough ideas by hand or in a simple tool. Quantity gets the obvious ideas out and makes room for original ones.
4. Refine a few concepts
Take the strongest three or four to vector software and develop them. Work in black and white first. If it works without colour, colour will only help.
5. Test
- Shrink it, invert it, view it on busy and plain backgrounds
- Show it to people from your target audience and ask what it suggests
- Check it next to competitors to ensure it is distinct
6. Finalise and deliver
Prepare a complete set of files so the logo can be used properly.
Files to deliver
- Vector masters (SVG, EPS or PDF) for unlimited scaling
- PNG exports with transparent backgrounds
- Colour variations: full colour, black, white
- Horizontal, stacked and icon-only versions
- App icon and favicon sizes
- A brief usage guide: clear space, minimum size and incorrect uses
Colour and typography in logos
Colour should reflect the brand but remain practical. Make sure a one-colour version exists for situations like stamps, embroidery or low-quality printing. Choose lettering that is legible at small sizes; very thin or ornate typefaces tend to disappear. If you use a font in a logo, check its licence permits that use, or customise the letterforms.

Common logo mistakes
- Too much detail, which becomes mush at small sizes
- Too many colours or effects such as gradients and shadows that do not reproduce well
- Following trends blindly
- Copying or resembling another brand, which can cause legal problems and confusion
- Using stock icons or templates that others also use, so the logo is not unique or ownable
- Poor spacing and alignment
- Not testing on real backgrounds and sizes
Always check trademark databases before committing, and consider professional legal advice for something you intend to protect.
Logo vs brand identity
A logo is one asset. A strong brand also needs colours, type, imagery, voice and consistent use. If you are a small team, a simple logo used consistently beats a complex one used inconsistently.

Final thoughts
A logo works when it is simple, distinctive and used with care. Invest time in the thinking before the drawing, and test it in the places it will actually live. If you would like a team to design your identity, see our brand design service or get in touch.
