Dear Ashim, I don't think the aspectratio is appropriate in this context because it would imply that the beamer (LaTeX) class is used but you're actually using the article (LaTeX) class.
You may use specifications of the geometry package rather than specifying options to the class: e.g. replace your current header: --- title: "Testing landscape and aspect ratio" output: pdf_document: number_sections: true classoption: - landscape - "aspectratio=169" header-includes: - \usepackage{dcolumn} documentclass: article geometry: margin=1.5cm --- with this one: --- title: "Testing landscape and aspect ratio" output: pdf_document: number_sections: true header-includes: - \usepackage{dcolumn} documentclass: article geometry: margin=1.5cm, paperwidth=24cm, paperheight=13.5cm --- Of course, you may change the exact dimensions and it will impact the relative font sizes. I've tested it and it generates what you want. Yours. Olivier.
