CSS Clamp Preferred Value Calculator
See the value produced when a preferred CSS size is constrained by a minimum and maximum.
How to use CSS Clamp Preferred Value Calculator
1. Enter Minimum Size, Preferred Size, Maximum Size. 2. All three values must use one compatible unit. This demonstrates numeric clamping; it does not parse CSS calc(), resolve mixed units or evaluate responsive CSS. Maximum must be at least minimum. 3. Select Calculate or press Enter. 4.

Why use this tool?
All three values must use one compatible unit. This demonstrates numeric clamping; it does not parse CSS calc(), resolve mixed units or evaluate responsive CSS. Maximum must be at least minimum.
How the calculation works
Numeric clamp = min(max(preferred, minimum), maximum). All three values must use one compatible unit. This demonstrates numeric clamping; it does not parse CSS calc(), resolve mixed units or evaluate responsive CSS. Maximum must be at least minimum. Counts and dimensions use the declared rounding convention; other numbers display up to three decimal places where applicable. Nonzero subsecond durations are labelled. Durations round to the nearest second; nonzero subsecond durations are labelled. File-size output units are decimal. Changing an input label does not convert filled values.
Example
Worked example: Minimum Size = 12; Preferred Size = 20; Maximum Size = 16. Result: 16.
Practical tip
Check the input labels and assumptions against the css clamp preferred value task before reusing the number.
