I was a bit outdated with resistor sizing and I don't have a great sources but apparently there are:

    inch 0402, 0201, 01005, 009005, 008004, $1
    mm   1005, 0603, 0402,  03015,  0201,   01005

these sizes... and $1 is the one in your mind that shall not be written in inches. The "01005 imperial" is just 0402, so it's not going up to the metric 01005 scale or beyond. I think.
