How to Use Upmost vs. utmost Correctly

The Difference between “Utmost” and “Upmost”

  • “Utmost” means “to the greatest extent.” For example:
  • I love Thanksgiving because it’s a holiday based on food and family, two things that are of utmost importance to me. (Chef Marcus Samuelsson)
  • “Upmost” means “at the highest position” or “uppermost.” For example:
    • Cut the upmost branch from the tree to protect the overhead power cable.


    Remembering the Difference

    One simple way to remember the difference between upmost and utmost is to consider the way they are spelled. Think of the T in uTmost as exTreme or greaTest.

    When remembering UPmost, think about the word UP. This will help you remember that “upmost” means the top position. You can think of the phrase “up top” to help you out with UPmost.

    How to Remember These Words

    If you are using the word to mean to the maximum, you should always use utmost. Upmost is considered incorrect in this context.

    Since utmost has an extra T, like most extreme, you should always be able to remember that utmost is the correct word in these instances.

    What does upmost mean?

    Upmost is a much less common variant of uppermost, and it means the same thing: highest in terms of physical height (the most up or most upper, if you will). Less commonly, it can mean highest in order, rank, or some other nonphysical quality. It can also mean the same thing as topmost, in the sense of predominant, as in a subject of uppermost concern (this is the sense that’s often closest to utmost).

    Upmost and the more common uppermost are both most commonly used in the context of the height of something, such as the upmost floor of a building. Still, it’s much more common to refer to this as the uppermost floor, the highest floor, or the top floor.

    How to remember the difference between upmost and utmost?

    Utmost starts with ut– (“out”), the same prefix found in the word utter (“complete, absolute”). Use the meaning of “ut” to remember how utmost can mean “furthest out” and the meaning of “utter” for when utmost describes “the greatest amount or extent possible.”

    Upmost vs. utmost is all about up vs. out.

    Utmost is typically used in contexts that involve things being at the utter limit or the outer limit. When you do your utmost, you go all out. The utmost point is the one that’s farthest out.

    Upmost, on the other hand, is usually about things that are the highest up—often in terms of physical height or priority (think of the top item on a list).

    If you’re describing something as being the greatest or the maximum among all options, either word might serve. But utmost is usually the right choice.

    Even though utmost can mean the same thing as highest, you wouldn’t use it to describe the top floor of a building. And, to be honest, you probably wouldn’t use upmost either (even though that’s what it properly means). In many cases, it may be best to replace upmost with uppermost, or topmost, or whatever word is clearest for a particular situation.

    In general, keep in mind that utmost is much more commonly used than upmost.

    Finally, here’s a handy synonym chart to help keep them straight.

    • utmost (as in greatest or maximum) = uttermost
    • utmost (as in farthest out) = outermost
    • upmost (as in highest up) = uppermost
