# RelativeSizeSpan

*** ** * ** ***

` public class RelativeSizeSpan `   
` ` ` ` ` extends https://developer.android.com/reference/android/text/style/MetricAffectingSpan ` ` implements https://developer.android.com/reference/android/text/ParcelableSpan `

|---|---|---|---|
| [java.lang.Object](https://developer.android.com/reference/java/lang/Object) ||||

*** ** * ** ***

Uniformly scales the size of the text to which it's attached by a certain proportion.

For example, a `RelativeSizeSpan` that increases the text size by 50% can be constructed like this:

    SpannableString string = new SpannableString("Text with relative size span");
    string.setSpan(new RelativeSizeSpan(1.5f), 10, 24, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

![](https://developer.android.com/static/reference/android/images/text/style/relativesizespan.png) Text increased by 50% with `RelativeSizeSpan`.
