Colorado felony sentencing follows a six-class system, Class 1 through Class 6, where the class of the offense sets the presumptive sentencing range a judge must impose unless aggravating or mitigating circumstances justify a departure. The statutory anchor for felony sentencing ranges is Colorado Revised Statutes section 18-1.3-401, and drug felonies instead follow a separate DF1 through DF4 framework.

How Colorado Felony Sentencing Works: The Class System
Colorado organizes felony sentencing around a class system, and understanding that structure is the foundation for understanding Colorado felony sentencing guidelines. At Law Offices of Robert E. Ray, we walk clients through this framework because the class of a felony drives the presumptive sentencing range, the available alternatives to prison, and the length of post-release supervision. Colorado law establishes six felony classes, each tied to a defined penalty tier under the Colorado Revised Statutes.
The Six Felony Classes and Their Penalty Tiers
Colorado divides felonies into Class 1 through Class 6, with Class 1 representing the most serious offenses and Class 6 the least serious. The Colorado Revised Statutes, criminal code set the statutory framework, and each class carries its own presumptive range, its own aggravated and mitigated ranges, and its own rules on probation eligibility.
A felony class is the statutory category that determines the range of punishment a court may impose. Class 1 felonies carry the harshest penalties and typically involve life imprisonment or the death penalty in limited circumstances.

Presumptive Sentencing Ranges and How to Read Them
The presumptive range is the band of punishment a judge must impose unless aggravating or mitigating circumstances justify departing from it. Colorado's felony sentencing guidelines build every sentence from this starting point: the presumptive range for the class, adjusted by the offender's criminal history and the specific facts of the case. The statutory anchor is Colorado Revised Statutes section 18-1.3-401, which sets the ranges for each felony class and the rules for departing from them.
The Statutory Ranges by Class
For offenses committed on or after the effective date of the current statutory scheme, the general felony ranges under Colorado law are commonly summarized as follows. These are the general ranges; offense-specific statutes can and do override them, which is why the class alone never tells the whole story.
- Class 1 felony: life imprisonment without the possibility of parole in the typical case, with the death penalty available only in the narrow circumstances the statute allows. There is no ordinary presumptive range in the Class 2-6 sense.
- Class 2 through Class 6 felonies: each carries a presumptive range set by statute, with fine ranges that vary by class. Confirm the current range and fine amounts for your specific offense at the official Colorado source before relying on them.
Each class also carries aggravated and mitigated ranges set by statute, so the outer boundaries of a lawful sentence are fixed before the sentencing hearing begins.
How to Read a Range in Three Steps
Reading a sentencing range correctly takes three steps:
- Identify the felony class of the offense, which sets the baseline range.
- Check the statutory exceptions for that specific offense, because some crimes carry their own ranges that override the general class rule. A handful of offenses are "extraordinary risk" crimes that carry a higher presumptive maximum than the class would otherwise allow.
- Apply criminal history, since prior convictions can push a defendant into a higher range or trigger habitual offender provisions.
A Worked Example
Suppose a defendant is convicted of a single Class 4 felony with no prior felony convictions and no extraordinary aggravating facts. The general presumptive range is 2 to 6 years. The judge may sentence anywhere in that band, say, 3 years, without making any special findings on the record. If the prosecution proves aggravating circumstances beyond the presumptive range, the court may impose a longer term within the aggravated range, but it must state the findings on the record. If the defense proves mitigating circumstances, the court may go below the presumptive range into the mitigated range, again with findings.
Watch out: a range is not a prediction. It is the legal boundary within which the sentencing judge exercises discretion, and the actual sentence depends on facts that are argued and documented at the hearing.
Where the Ranges Come From and How They Change
The ranges are statutory, which means they change when the legislature amends the statute. A range that appears in an older reference chart may no longer be current. Before relying on any range, confirm the effective date of the statute that applies to the offense conduct, because the version of the law in effect on the date of the offense generally controls.
Class 4 Felony Jail Time and What to Expect
Class 4 felony jail time in Colorado falls within a defined presumptive range, and the actual sentence depends on criminal history, the nature of the offense, and whether the court finds grounds to depart. Class 4 felonies sit in the middle of the felony ladder, serious enough to carry real exposure but often eligible for alternatives to prison for first-time offenders.
What most people miss is that "jail time" and "prison time" are not interchangeable in Colorado sentencing. County jail typically applies to misdemeanor sentences and short-term holds, while felony sentences of incarceration are served in the state prison system unless the court imposes community corrections.
A common mistake is assuming a plea to a lower class automatically means no incarceration. The class sets the range, but the sentencing judge still decides where within that range the sentence lands.
Mitigating and Aggravating Factors That Shift a Sentence
Colorado also recognizes extraordinary aggravation and extraordinary mitigation, which allow a court to depart from the presumptive range when the circumstances are exceptional. When a case involves allegations of violence, the aggravating factors can reshape the entire sentencing analysis, and our violent crimes defense team examines those factors before a sentencing hearing.
The nature of the offense and the character and record of the offender are the two anchors Colorado courts return to again and again. Both are argued, documented, and contested at sentencing.
Drug Felony Sentencing: A Separate Framework
Drug felonies in Colorado follow their own classification system rather than the Class 1 through Class 6 ladder used for other offenses. Colorado assigns drug felonies to levels DF1 through DF4, and each level carries its own presumptive range, its own fines, and its own eligibility rules for probation and diversion. The framework lives in a separate article of the Colorado Revised Statutes, controlled substances, which is why a drug charge requires its own sentencing analysis rather than a lookup on the general felony chart.
The Four Drug Felony Levels
For offenses under the current statutory scheme, the general drug felony ranges are commonly summarized as follows. As with the general felony classes, offense-specific rules and quantity thresholds can modify these ranges, so the level alone is not the whole answer.
- DF1: the most serious drug felony level, carrying the longest presumptive exposure and the largest fines. DF1 is reserved for the highest-quantity and highest-conduct offenses, and probation eligibility is narrow.
- DF2: a mid-tier drug felony with a presumptive range below DF1 but well above the lower levels, and fines scaled to the level.
- DF3: a lower-tier drug felony that often allows probation and treatment-based dispositions for eligible defendants.
Each level carries its own presumptive, aggravated, and mitigated ranges, and the same three-step reading process applies: identify the level, check the offense-specific statutory exceptions, then apply criminal history.
What Drives the Level
The quantity and type of controlled substance, the defendant's role in the offense, and prior drug convictions can all influence which level applies, and quantity thresholds are set by statute. A defendant's role, courier versus organizer, for example, can also move the analysis, and prior drug convictions can trigger enhancement provisions that change the applicable range.
Probation, Diversion, and Treatment Alternatives
Probation, diversion, drug court, and treatment-based sentences depend on the level and on statutory eligibility, and the court considers the defendant's criminal history and the nature of the offense before granting them.
Watch out: assuming a drug charge will be treated like a general felony of similar seriousness. The drug framework runs separately from the general classes, so the applicable statute and level matter.
How the Drug Framework Interacts with the General Classes
Because the drug framework runs parallel to the general felony classes, a drug charge requires its own sentencing analysis. Some drug offenses carry mandatory minimums or enhancement provisions that override the general level range, and some conduct can be charged under either the drug statutes or a general offense depending on the facts. Our guide on avoiding jail time for drug charges explains the strategies defendants and their counsel use at this stage.
Mandatory Minimums, Parole, and Post-Release Supervision
Mandatory minimums remove discretion from the sentencing judge for certain offenses.
Parole follows incarceration. Colorado imposes a period of parole after a prison sentence, and the length of that parole period depends on the statute governing the offense.
Community corrections is a possible alternative to prison, and eligibility depends on the offense and the defendant's history. Check the official Colorado source for current eligibility rules.
Preparing for a Sentencing Hearing with a Defense Attorney
A sentencing hearing is the proceeding where the judge imposes sentence after a conviction or plea, and preparation for it begins long before the hearing date.
Preparation generally involves assembling the record that supports mitigation, such as treatment records, employment history, letters of support, and evidence of rehabilitation.

Frequently Asked Questions
What are the different classes of felonies in Colorado?
Colorado divides felonies into six classes, from Class 1 (the most serious) to Class 6 (the least serious). Class 1 felonies carry the harshest penalties, while Class 6 felonies carry the lightest. Each class has a set presumptive sentencing range that judges use as a starting point. The class of the felony sentencing charge depends on the specific offense and how the statute classifies it.
How does the presumptive sentencing range work for felonies?
The presumptive sentencing range is the standard penalty range a judge must consider for a given felony class. For example, a felony has a presumptive range set by statute for its class, and a judge can depart from that range only if aggravating or mitigating factors justify it. Understanding presumptive sentencing ranges helps you anticipate the likely outcome and prepare arguments for a lower sentence.
What factors influence a judge's sentencing decision?
Judges weigh many factors, including the nature of the offense, the defendant's criminal history, character and record, and any mitigating or aggravating circumstances. The presence of prior convictions, the use of a weapon, or the vulnerability of the victim can increase a sentence, while remorse, cooperation, or rehabilitation efforts can reduce it. An experienced attorney can present evidence to highlight mitigating factors.
What is the difference between a presumptive sentence and an extraordinary risk sentence?
A presumptive sentence falls within the standard range set by statute for the felony class. An extraordinary risk sentence is a departure above the presumptive range, allowed when aggravating circumstances are present. The judge must make specific findings on the record to justify an extraordinary risk sentence. Similarly, a mitigated sentence falls below the presumptive range when mitigating factors are proven.
How does mandatory parole affect a felony sentence?
Mandatory parole is a period of supervision that follows release from prison for certain felonies. It follows the prison term under the governing statute, and its length depends on the statute and the offense. Violating parole can lead to re-incarceration, so it is important to understand the conditions before release.
Can a felony sentence be reduced or modified?
Yes, a felony sentence can sometimes be reduced or modified through post-conviction motions, appeals, or a request for early release. Grounds may include errors at sentencing, newly discovered evidence, or a change in circumstances. An attorney can review your case to determine if a sentence modification is possible and file the appropriate motions with the court.
