In MODERN Tagalog (Tagalog-English adaptation), "aspect ratio" is "aspect ratio" but you can also say "rasyo ng aspeto" ng isang bagay. (Aspect = Aspeto | Ratio = Rasyo | They are most commonly known as "cognates.") BUT, You will rarely hear "rasyo ng aspeto" being used in real/daily life. Some people do not even know what that is. We normally just use either "dimensyon (dimension)" or "sukat (measurement)" as a general term. We probably have a specific word for "aspect ratio" in OLD or ANCIENT Tagalog, but it may have already been buried in one of the books of the National Library of the Philippines. I asked my 90 year-old grandpa who used to work as a carpenter. He is still strong, agile and alert, but he also doesn't know the specific/pure tagalog of those words. :)

In addition to my first answer, if you want to simply say 4:3 (where 4 is the height and 3 is the width), we read it as "four BY three." 2:2 is either "two BY two", or "dos POR dos" (depending on the object you are describing) Alternatively, we write it as 4x3 or 2x2.
