**Note**  
 AWS WAF Classic support will end on September 30, 2025.   
This is ** AWS WAF Classic** documentation. For more information, see [AWS WAF Classic](https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html) in the developer guide.  
 **For the latest version of AWS WAF **, use the AWS WAFV2 API and see the [AWS WAF Developer Guide](https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html). With the latest version, AWS WAF has a single set of endpoints for regional and global use. 

A complex type that contains `SizeConstraint` objects, which specify the parts of web requests that you want AWS WAF to inspect the size of. If a `SizeConstraintSet` contains more than one `SizeConstraint` object, a request only needs to match one constraint to be considered a match.

 ** SizeConstraints **   <a name="WAF-Type-wafRegional_SizeConstraintSet-SizeConstraints"></a>
Specifies the parts of web requests that you want to inspect the size of.  
Type: Array of [SizeConstraint](API_wafRegional_SizeConstraint.md) objects  
Required: Yes

 ** SizeConstraintSetId **   <a name="WAF-Type-wafRegional_SizeConstraintSet-SizeConstraintSetId"></a>
A unique identifier for a `SizeConstraintSet`. You use `SizeConstraintSetId` to get information about a `SizeConstraintSet` (see [GetSizeConstraintSet](API_wafRegional_GetSizeConstraintSet.md)), update a `SizeConstraintSet` (see [UpdateSizeConstraintSet](API_wafRegional_UpdateSizeConstraintSet.md)), insert a `SizeConstraintSet` into a `Rule` or delete one from a `Rule` (see [UpdateRule](API_wafRegional_UpdateRule.md)), and delete a `SizeConstraintSet` from AWS WAF (see [DeleteSizeConstraintSet](API_wafRegional_DeleteSizeConstraintSet.md)).  
 `SizeConstraintSetId` is returned by [CreateSizeConstraintSet](API_wafRegional_CreateSizeConstraintSet.md) and by [ListSizeConstraintSets](API_wafRegional_ListSizeConstraintSets.md).  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 128.  
Pattern: `.*\S.*`   
Required: Yes

 ** Name **   <a name="WAF-Type-wafRegional_SizeConstraintSet-Name"></a>
