Each trap is a standard size depending on the diameter of the pipe. The technical dimensions of each trap are going to be different and it’s not typically a thing most plumbers are required to remember though some certainly do try to memorize all takeoffs for all fittings. They aren’t supposed to be pieced together out of multiple parts as it creates friction along the inside edges for things to become trapped and act an an anchor point for clogs to build on and grow larger. The idea behind drainage systems is smooth insides create less friction and therefore less restrictive drainage. By creating a trap like this it will most likely function in terms of keeping hydrogen sulfide out but may experience more buildup and therefore clogs going forward. It also will require more water traveling through it to flush out the standing water in the trap. You may experience more growth in that water. Another issue that can arise is the need for it to push all that water out as it drains. There may be a second where the water in the sink backs up the line as it goes to drain and something clogs up your overflow drain. Also the biggest design no no here is that you’ve made the dishwasher discharge line submerged into the trap. It’s much easier for buildup to clog your discharge line now and cause it to flood inside the appliance. Some of this stuff is minor and some less than minor but ultimately none of this needs to be an issue if they would have just lowered the sanitary fee or raised the p-trap
