It depends on what you define as "the size of government".
If you define it as government spending, every administration has spent more than the last because the population increases drive spending increases in programs and services. While the size of the budget does indicate the "size of government" in regards to what percentage of GDP does it take to run the country, it doesn't accurate reflect the impact of governmental structures on people's lives.
But if you look at how many goverenment workers there are under each president, that's is how you gauge the "size of government". This is from 2020.........................
The true size of government is nearing a record high | Brookings
As the federal government has hovered close to two million employees for decades, the size of its grant and contract workforce has grown.

"President Barack Obama entered office with the Great Recession raging and the true size of the federal workforce at about 10 million civil servants, postal workers, active duty military, contractors, and grantees. He raised the total with billions in economic stimulus to 11.3 million, then backed it down to about 9 million before leaving office. With the economy in full-throated rebound, Obama gave Donald Trump the rare opportunity to rebalance the federal government’s blended workforce.
Despite campaign promises to the contrary, Trump opened the contract and grant spigots instead, adding more than 2 million jobs to the blended federal workforce, including 1 million in the Departments of Defense, Transportation, and Health and Human Services alone."
Scroll down the page to the graph, and you will size that the size of government workforce declined under Clinton and Obama, and went up under every Republican Administration, including Trump's.
Trump loved the government contracts. He handed out over 200 of them to members of his east coast golf clubs, and corporations who booked events at his Washington Hotels. The ten camps holding the refugee claimants were built and run by for profit prison companies who donated heavily to his Inauguration Fund. $100 million in donations which were never accounted for.
