This is a post about template for Latex beamer presentation. Actually it’s really fun to use (better than powerpoint for sure) There are many options for theme but the moist important is to sort the aspect ratio.
\documentclass[
11pt, % Set the default font size, options include: 8pt, 9pt, 10pt, 11pt, 12pt, 14pt, 17pt, 20pt
t, % Uncomment to vertically align all slide content to the top of the slide, rather than the default centered
aspectratio=169, % Uncomment to set the aspect ratio to a 16:9 ratio which matches the aspect ratio of 1080p and 4K screens and projectors
]{beamer}
\usepackage{booktabs} % Allows the use of \toprule, \midrule and \bottomrule for better rules in tables
