How to choose PPT background

1. Don't use too fancy large-area colors for PPT background images of large conferences. A light blue or gray background is recommended. The decorative elements of the picture should also be smaller in area and simpler in color.

2. The theme words of the conference can be bigger, the font is thicker, and the contrast between color and background is bigger. So you can see it from a distance.

Notes on PPT background and font matching:

First, the text is concise:

The text content on the courseware is just like a blackboard writing, which cannot be too much, too long, too thin, too miscellaneous, too miscellaneous and too messy; It is not appropriate for multiple questions to occupy one page; Full-screen display is not recommended; do not leave margins; The same page should not have too many fonts; The title is too small and the text is too large, which is not desirable; Too many colors and messy words are not desirable.

The number of words in a single slide should be between 30 and 60 Chinese characters. If there are many questions or concepts, a slide will be split into two if it can't fit. Don't pile up words on the slide. In short, the theme is clear, detailed, concise and just right.

Second, the mixed arrangement of pictures and texts is reasonable:

Pay attention to the key points when mixing pictures and texts, don't let other accessories of the foil usurp the role of the master, and try not to cover the text on the pattern. When there are multiple pictures in a page at the same time, there should be no overlap between the pictures. Try to align them as much as possible, or arrange them according to certain rules with moderate tightness.

Third, the background is elegant and should not be messy.

The background of each slide in the presentation should be consistent or basically the same, and one background is not effective; The background color is elegant, not fancy and messy; The color contrast should not be too big, and the number should not be too much; No matter how beautiful the picture is, the background effect will not be very good. Remember that the background is always a supporting role in the presentation, and don't usurp the role of the host.

Fourth, the color matching is reasonable and fresh.

The colors of the slides are fresh and beautiful. The background color, title color, text color and hyperlink text object color should be reasonable, fresh and bright, but not too messy. Like the design of web pages, PPT is also taboo "colorful". Too many colors will appear messy and distract students.

Generally speaking, there are at most three colors besides black and white. It is suggested that each courseware should be prepared with two colors to adapt to different ambient light. The first type of white characters with blue background is suitable for use in the case of ambient light intensity. This kind of color collocation can not only make students see the words clearly, but also make students less prone to visual fatigue. The second type of black characters with white background is suitable for use in dark environment, because the white background can make students see the teacher's "body language" clearly.
