Corridor width standard
The corridor leading to the auxiliary room in the house is only 0.8m wide, which is called "one-way street" and only one person is allowed to pass. The corridor leading to the bedroom and living room should be wider, at least 1m, so that two people can pass sideways.
* * * building corridor width
The aisle width of high-rise residential buildings and public buildings is usually greater than 1.2m to meet the demand of two people in parallel. This design can better meet people's travel needs and improve the efficiency of the building.

If you have any questions about the width of your corridor, these data may be helpful to you. I hope these materials can help you better understand the design specifications of residential corridors.
