As of the 2022 season, NFL practice squads hold 16 players, a size made permanent after it was temporarily adopted during the COVID-19 pandemic in 2020. The 2020 collective bargaining agreement had set the limit at 12 starting in 2020, rising to 14 in 2022, but the pandemic-era expansion to 16 was kept.

The International Player Pathway (IPP) is an NFL program created in 2017 to bring players from outside the United States onto practice squads as extra members who do not count against the normal roster limit. It began as a trial with NFC South teams, expanded to eight teams in 2018, and opened to all NFL teams in 2024. Starting in 2024, IPP players can also be elevated to gameday rosters for up to three games per season.
