EDMONDS, P.J.
Defendant pleaded guilty to two counts of first-degree forgery. ORS 165.013.[1] He appeals *770 from consecutive sentences of 24 months for each count, followed by a one-year term of post-prison supervision. We reverse.
In October 1996, defendant deposited into his bank account a $1,000 check that he had endorsed and that had belonged to a recently deceased person. In December 1996, he deposited another $1,000 forged check belonging to that person. Eventually, defendant was convicted of forgery as the result of his conduct. His convictions required sentencing under OAR chapter 213 (1996). ORS 137.010(1). In the plea agreement that led to his convictions, defendant and the prosecutor agreed that, for a Level 3 forgery, the appropriate crime seriousness ranking was a 3. OAR XXX-XXX-XXXX(2) (1996); OAR ch. 213, app. 3 (1996).[2] They also agreed that the criminal history category was a "B." OAR XXX-XXX-XXXX (1996). The relevant presumptive sentence for a 3B conviction provided for a two-year term of probation. OAR XXX-XXX-XXXX(1)(b) (1996); OAR ch. 213, app. 3 (1996). However, the court found four aggravating factors at sentencing: persistent involvement in criminal activity; multiple prior probation failures; a particularly vulnerable victim; and that defendant was under post-prison supervision at the time of the offenses. Ruling that any two of those factors would suffice as grounds for a dispositional and durational departure, the court sentenced defendant to 24 months of incarceration for each conviction in accordance with OAR XXX-XXX-XXXX through OAR XXX-XXX-XXXX (1996). In addition, the court ordered that the sentences be served consecutively, after finding that the offenses occurred on different dates and were not part of the same criminal episode. Also, the court imposed a one-year term of post-prison supervision as required by OAR XXX-XXX-XXXX(2)(a) (1996).
On appeal, defendant argues that his sentences violate the proportionality requirement of Article I, section 16, of the Oregon Constitution.[3] He asserts that, if he had committed Level 4 forgeries, the maximum durational departure sentence with a "B" criminal history score would have been 18 months in prison. Article I, section 16, prohibits the imposition of a sentence for a lesser offense that is greater than that available for a more serious offense. State v. Turner, 296 Or. 451, 456, 676 P.2d 873 (1984); Merrill v. Gladden, 216 Or. 460, 464, 337 P.2d 774 (1959); Cannon v. Gladden, 203 Or. 629, 631-33, 281 P.2d 233 (1955).
The parties agree that the presumptive sentence for first-degree forgery involving amounts over $5,000 was eight to nine months of incarceration as found in gridblock 4B. OAR ch. 213, apps. 1 and 3 (1996). A sentencing court could impose a maximum of 18 months of incarceration for that offense after finding grounds for departure. OAR XXX-XXX-XXXX(2) (1996). In addition, the required term of post-prison supervision was two years. OAR XXX-XXX-XXXX(2)(b) (1996). The state asserts that:
"A sentence is not disproportionate whenever a longer sentence may be imposed for a lesser offense, and the sentencing guidelines do not require a longer sentence for a lesser offense for a defendant with a B criminal history ranking. Moreover, even if defendant were correct that a sentence is disproportionate any time a more severe *771 sentence is possible for a lesser offense under a particular sentencing scheme, defendant did not necessarily receive a more severe sentence than he would under gridblock 4-B. The total supervision time imposed as part of the maximum departure sentence permissible under gridblock 3-B is shorter than the total supervision period for the maximum departure sentence under gridblock 4-B." (Emphasis in original.)
As we understand the state's first argument, the fact that the trial court had discretion to depart from the presumptive sentence means that the departure sentence was not "required" within the meaning of the proportionality doctrine. According to the state, a sentence is constitutionally disproportionate only if the statute under which the sentence is imposed requires a greater sentence for a particular offense than required for a more serious offense. The state's premise is incorrect.
Under Article I, section 16, we compare the actual sentence imposed to the maximum sentence allowed by law for the greater offense to evaluate a disproportionality challenge. Turner, 296 Or. at 457, 676 P.2d 873; Merrill, 216 Or. at 463, 470, 337 P.2d 774; Cannon, 203 Or. at 630, 632-33, 281 P.2d 233.[4] In Turner, Merrill, and Cannon, the trial court had the discretion to impose other sentences on the defendants. Nonetheless, the court focused on the sentence imposed in each case. In Turner, the defendant was convicted of attempted rape in the first degree. The applicable statutes established a maximum limit on an indeterminate sentence for a dangerous offender and permitted the trial court to impose a minimum sentence of up to one-half of the sentence. 296 Or. at 453-54, 676 P.2d 873. The trial court imposed the maximum indeterminate sentence for a dangerous offender and one-half of that maximum as a minimum sentence. Id. On appeal, the defendant argued that his sentence was disproportional to the life sentence provided for a murder conviction. The court held that "[a] sentence for the remainder of a person's life is a greater sentence than a 30-year sentence with a 15-year minimum." Id. at 457, 676 P.2d 873. The court refused to speculate on Parole Board practices for the setting of release dates or to engage in any considerations about the possible length of any particular defendant's life. Instead, the court emphasized that in analyzing constitutional proportionality challenges: "[w]e examine only the sentences as imposed by the trial judge." Id.
Likewise, the court in Merrill focused on the 20-year sentence imposed upon the defendant when comparing that sentence to a more serious crime, although the trial court could have used a permissible range of sentencing options for the lesser crime of "not less than one nor more than twenty years." 216 Or. at 463, 470, 337 P.2d 774. In Cannon, the defendant argued that his sentence for assault with intent to commit rape was unconstitutionally disproportionate in comparison to the sentence available for rape. The defendant received a life sentence under a statute that according to the court "fixed the penalty for assault with intent to commit rape at life imprisonment in the penitentiary or for a period of not more than 20 years." Cannon, 203 Or. at 631, 281 P.2d 233. The statute governing the more serious crime, rape, provided that a convicted defendant "may be sentenced to the penitentiary for not more than 20 years." Id. at 630, 281 P.2d 233.
The court concluded:
"How can it be said that life imprisonment for an assault with intent to commit rape is proportioned to the offense when the greater crime of rape authorizes a sentence of not more than 20 years? It is unthinkable, and shocking to the moral sense of all reasonable men as to what is right and proper, that in this enlightened age jurisprudence would countenance a situation where an offender, either on a plea or verdict of guilty to the charge of rape, could be sentenced to the penitentiary for a period of not more than 20 years, *772 whereas if he were found guilty of the lesser offense of assault with intent to commit rape he could spend the rest of his days in the bastile." Id. at 632-33, 281 P.2d 233.
The above quoted language from Cannon demonstrates that the court applied a comparison between the actual sentence imposed and the maximum available for the greater crime. Thus we reject the state's first contention, that the periods of imprisonment are not disproportional, and turn to its second assertion that we should consider the periods of post-prison supervision in making our comparison.
In State v. Shumway, 291 Or. 153, 164, 630 P.2d 796 (1981), the defendant was convicted of intentional murder and sentenced to life with a minimum of 25 years of incarceration before being eligible for parole under the statute in effect at that time. The court compared that sentence with the sentence a defendant could have lawfully received if convicted of aggravated murder, a more serious offense. Shumway, 291 Or. at 164, 630 P.2d 796. The maximum sentence for that crime carried a 15- or 20-year minimum period of incarceration before a defendant was eligible for parole. Id. at 158, 160, 164, 630 P.2d 796. The court held:
"Under this statutory scheme, a defendant receives a lesser minimum sentence to be served before being eligible for parole for aggravated intentional homicide than he does for an unaggravated intentional homicide. This is in violation of Art I, § 16 of the Oregon Constitution and that provision * * * requiring the defendant to serve not less than 25 years before becoming eligible for parole is invalid and cannot be applied to the defendant; the statutory provision requiring a life sentence is valid." Id. at 164, 630 P.2d 796 (emphasis added).
Shumway stands for the proposition that, for section 16 purposes, the comparison is between the amount of incarceration actually imposed and the maximum authorized sentence for the greater offense and that the consideration of lengths of parole or possible sanctions for the violation of parole does not enter into the calculus. Accord Turner, 296 Or. at 457, 676 P.2d 873. It was neither dispositive nor relevant to the court in Shumway that both the murder statute and the aggravated murder statute required a convicted person to receive a life sentence and that, under both, Shumway could presumably be returned to prison after release for the remainder of his life for a violation of the terms of parole. See ORS 144.343(2)(b) (1979). Similarly, the period of post-prison supervision and the possible sanction for a violation in this case are not relevant to our analysis under section 16.
The state relies on State v. Rice, 114 Or. App. 101, 107 n. 6, 836 P.2d 731, rev. den. 314 Or. 574, 840 P.2d 1296 (1992), for the proposition that the period of post-prison supervision should be included in the comparison between the two sentences. In Rice, the defendant was convicted of seven counts of negotiating a bad check, a misdemeanor, and received 90-day sentences for each count. The relevant statute allowed the trial court to exercise discretion in sentencing on a misdemeanor, so long as the sentence did not exceed six months. The defendant argued that his sentence was unconstitutionally disproportionate under section 16, because the presumptive sentence under the sentencing guidelines for first-degree theft, a felony, was probation. We upheld the sentence, concluding that under a misdemeanor statutory scheme that did not require the imposition of any sentence when compared with a statutory scheme that mandated the imposition of a sentence of probation for a felony, no proportionality problem occurred under section 16. Rice, 114 Or.App. at 107, 836 P.2d 731. We do not believe that the holding in Rice is controlling in this case where the trial court was required to impose either a presumptive or departure sentence of determinate duration for a felony. Here, the comparison is between two different levels of the same felony and presents the same situation addressed by the court in Shumway.
In conclusion, the maximum sentence that defendant lawfully could have received would have been a 18-month term of incarceration if defendant had been convicted of forging a $5,000 check and if the sentencing court had found grounds for a departure sentence. Because *773 the sentencing court imposed a 24-month term of incarceration for a less serious level of forgery on each conviction, the sentences violate Article I, section 16.
Reversed and remanded for resentencing.
