The amount of memory accessible from the TLB.
TLB Reach = (TLB Size) X (Page Size).
The working set of each process is stored in the TLB, Otherwise there is a high degree of page faults.

Increase the Page Size : This may lead to an increase in fragmentation as not all applications require a large page size
Provide Multiple Page Sizes : This allows applications that require larger page sizes the opportunity to use them without an increase in fragmentation
