Tips on making good slides
What Font size should you use?
- You can estimate how your slide will appear by looking at your computer
screen from the right distance.
- Use the equation: Distance from the
computer screen = (distance to the back row/ auditorium screen height)x(computer screen
- An average auditorium screen is 6 feet high. The distance to the last row
of seats 36 feet. Suppose your computer screen is 8 inches high. In this case
- Distance from the computer screen = (36/6)*8 = 48 inches = 4 feet

- For most talks, the minimum font size
is about 24 (about 42 characters across and 14 lines down) and the minimum line thickness is about .01 to 02 inches.
What Font type should you use?
For sentences use Serif. For example:
- Why? Because these fonts make it easier to bind the letters into words
- Often good to bold and double space.
However most slides should aviod sentences and paragraps
and instead use point form.
Thus most slides use Sans Serif. For example:
- Why? Because these fonts are simpler.
An example of a slide with not enough contrast between the elements and
- Be very careful to maintain sufficient
contrast between the figure and the background.
- When composing slides on a computer, the colors on the screen can be
misleading. The screen underestimates the contrast (and minimum line thickness) that a
slide requires, particularly in a big auditorium. Test run a few slides in the size of the
auditorium you will use.
- If you use a dark background, use very light colors for lines and text.
- If you use a light background, use very dark colors for lines and text.
Use color effectively.
- Use bright colors for the
few most important elements.
- Use dull colors (black,
brown) for things that should be unobtrusive.
||Do not forget to add labels.
- You may forget to mention what the lines mean or your listener may not
have been listening.
