It's best to go to the magazine official website to see the submission instructions and other people's requirements for the manuscript. Most magazines will give a paper template, which details the typesetting requirements, title font size requirements, article language, content structure requirements, author and fund information. Doc format is generally specified, depending on the magazine. If there is no requirement of double columns in the submission requirements, but the articles published in this journal recently are all double columns, it is recommended to typeset them into double columns.
