A misdemeanor is less severe than a felony offense. Consequences from a misdemeanor can include fines, a county jail sentence, and community supervision. Depending on the crime, misdemeanors will be classified as Type A (more serious) and Type B (slightly less severe), and result in lower punishment than a felony. Often times, possession crimes, driving crimes, and public offenses are classified as misdemeanors.
A felony is a very serious crime, a conviction of which will impact your whole future. Felonies can result in anywhere from ten years community supervision to life in prison, with potential for parole or probation.
Additionally, prospective employers are more likely to deny employment to a person with a felony conviction, and state laws are more restrictive regarding the ability of a felon to get a state license for certain occupations. Theft crimes, violent crimes, and many white collar crimes are classified as felonies.
