What size wire and subpanel for a pergola with an outdoor kitchen?
You should really have done this calculation before installing the conduit but a 1" will be sufficient for what you want to do.

The answer is: the sub-panel needs to be sized large enough to carry the calculated load of all of the appliances, lights, fans, and plug connected loads. If you have all 120 volt loads you can either add up all the currents and then divide by 2 since you are splitting the load between two conductors on a 240 volt panel, or add up all the wattages and divide by 240 to get the max current on the feeders to the sub-panel.

Most of what you listed are very small loads except for the crock pots and other possible plug connected loads that can be manufactured as high as 1500 watts for 120 volts. (I am thinking of a resistive charcoal starter.) So, I would calculate the receptacles at a minimum of 1000 watts per if you plan to have mixed loads at that location.

All that said there are only a few basic sizes for sub-panels and a back-of-the-envelope calculation tells me you could have as small as a 60 amp panel here with #6 wire feeding it. Now, if you want some room (ampacity) to add on in the future and have big plans to grow your outdoor kitchen, you may want to go with a 100 amp panel fed with #3.

Now it comes down to personal preference.

Good luck and happy grilling.
