From CNBC:

The charges against Trump are Class E felonies, the least serious category under New York law. Each count carries a maximum sentence of four years in prison.

Experts tend to think it is highly unlikely that Trump will face any jail time as a result of the hush money verdict. “I’d be shocked” if Trump is sentenced to jail, Bachner said. He added that a sentence of probation would be normal for the average defendant convicted of the same crime. [Judge] Merchan has made clear throughout the trial that he is mindful of Trump’s unique political status, and he has previously expressed reluctance to put the ex-president behind bars.

Gershman told CNBC that a jail sentence is “certainly plausible,” and that it “would not be out of bounds” for Merchan to sentence Trump to some time behind bars. But he acknowledged that, due to the immense and complex challenges of incarcerating a former president, the judge might instead opt for a sentence of house arrest. “This case goes to the heart of our democracy, according to the judge,” Gershman said. “He views this case as very, very serious.”
