Keep in mind the amount of space you have to work with. You'll probably start with way too much text, and you’ll need to cull down the material.
In the brochure copy itself, try to:
- Keep to one idea per paragraph.
- Use short sentences.
- Use bullet points where possible to free up as much white space as possible.
- Divide the text into clearly labeled sections
Charts and graphs should be simple in design and clearly illustrate a point. A simple explanation under the chart should be all you need to make your point.
Adjust the different elements to make everything fit and flow properly. A cramped brochure looks bad and is less likely to be read.
Proofread the piece for misspellings or grammatical errors.
