I want to build a ramp up the two steps to my front door so that I can bring
my mom into my house.

I built one for my daughter while she was recovering from an accident. Internet
research showed that 1" of rise in 12" of run was the maximum, with 1" in 20"
being better. I built a 1 in 12 ramp. She could not get up it using her hands
on the wheels, but could back up it by pushing with her good leg. She was 30 at
the time and in good condition. It was mildly difficult for me to push her up.

In summary, I'd recommend a 1 in 20 ramp if possible.
