The present USA voltage standard range is 120/240VAC 60Hz at +-5%, and has been for many years. There are exceptions to this in large buildings, where polyphase systems are sometimes used, but standard single phase residential and light commercial is all 120/240 service. We haven't had 110/220 for well over 60 years.
There is a tolerance and the actual measured voltage is rarely exactly 120 volts. A common reading at my house is 117 volts. Industrial motors are made and rated in multiples of 115V (115, 230, 460, and 550Vac) for use on line voltages in multiples of 120 V (120, 240, 480, and 600 Vac).
