Properties of two-dimensional thermal radiation are investigated as a function of sample size and temperature. The two-dimensional thermal radiation is different from two-dimensional blackbody radiation when the size of the sample becomes small due to the uncertainty principle, which shows the allowed minimum energy can't be neglected. The energy density is shown as a function of sample size at a constant temperature. The energy density is also shown as a function of temperature at a constant size. It is shown that our prediction can be measured from the thermal radiation of graphene.
