It really varies. It can take anywhere from 10 to 60 minutes (and more in some cases) to do the research, gather the information, and write the text for a single slide. And it can take anywhere from 10 to 60 minutes (and more if you need to make charts, graphs, etc.) to put it on a slide and polish it.
Depends on the purpose. If it`s an internal presentation for a daily I will not spend much time and effort on it, so it is about 1-1.5 h.
But if it`s a presentation for the client or another type of external presentation I can spend on it from 3 to 10 hours or even more!
@vimal_kutmutia Your presentation looks fantastic! My team and I are preparing to launch a service to speed up your work. According to our calculations, designing the slides takes 1 to 3 minutes. I hope you will try it soon. It will be interesting for us to listen to your feedback :)
Usually, if the presentation is not very complex, then I can do it myself within a few hours. However, if we are talking about professional material, and I need high-quality business presentation design then I am used to ordering such work from experienced, qualified specialists. It seems to me that this is the best option for me, since I don’t always have enough time to complete such complex work.
