This varies widely and depends on several factors including the Journal or submission site in question, the type of paper, the scope of the topic, etc. It could be anything from as short as a month to a over a year.

Hi, Fayez,

You might get an idea of the turnaround for a specific journal by looking at the date submitted and date published. Many journals include this information on every published paper.

From month to over a year depends on several factors....

Best wishes,

It depends on many factors such as editorial processing, reviewers availability and journal production rate.
