What is the diameter of observable universe?

I see again & again in your posts that you recommend the Wright Calculator.
OK maybe for professionals in this field - but for lesser mortals with maybe a science degree, engineering degree or similar, well frankly this calculator is utterly unconvincing.
First, we are all trained not to blindly calculate without a good understanding of the assumptions that may be involved, & that always we should have the means or experience to judge the result as acceptable or not.
Now I have looked at this calculator & conclude it is totally inappropriate for use by anyone not suitably trained or supervised. This clearly includes many of the people to whom you refer this site & it includes myself.
In fact I think for the purpose it was probably intended it is archaic in design (pathetic GUI) & lacking the guidance notes or even the symbol definitions you might expect to find.
I have not studied all Prof Wrights tuts but some of his other posted material suffers similar shortcomings.

The observable universe is the portion of the entire universe that can be seen from Earth. This includes all matter, energy, and light that has had enough time to reach us since the beginning of the universe.
The diameter of the observable universe is estimated to be about 93 billion light-years. This means that it would take light 93 billion years to travel from one end of the observable universe to the other.
Scientists use various methods, such as measuring the cosmic microwave background radiation and the redshift of galaxies, to calculate the diameter of the observable universe. These measurements are then used to estimate the distance to the edge of the observable universe.
Yes, the diameter of the observable universe is constantly changing. This is because the universe is expanding at an accelerating rate, causing objects to move further away from each other over time.
No, the observable universe is only a small fraction of the entire universe. It is believed that the universe is much larger and may even be infinite in size, but due to the limitations of the speed of light, we can only observe a certain portion of it.
