This is a question frequently asked, Is our Universe Infinite? Here is a report that may illustrate how difficult it is to verify a correct answer here
ARE THESE THE MOST DISTANT GALAXIES YET SEEN?, https://skyandtelescope.org/astronomy-news/are-these-the-most-distant-galaxies-yet-seen/
Apparently z=13.27 is now measured

My observation. Using this cosmology calculator, https://lambda.gsfc.nasa.gov/toolbox/tb_calclinks.cfm
with defaults and z=13.27, age at z = 0.323 Gyr, look back distance or light time distance = 13.399 Gyr, and comoving radial distance = 33.420 Gly. 33.420 Gly is the 4D space position now showing expansion > c velocity, hyperspace coordinate. We cannot see 33.420 Gly out from earth according to Special Relativity. Using this cosmology calculator, https://www.kempner.net/cosmic.php
, z=13.27 with defaults, age of universe at z = 0.319685 Gyr, look back time distance = 13.5102 Gyr, comoving radial distance = 10232 Mpc = 3.3372321E+10 LY or 33.372 billion light years distance. Thus 4D space expanding faster than c velocity using hyperspace coordinate to explain such large redshifts using the BB model. Using 13.4 billion light-years distance, a galaxy with diameter 50,000 light years = 1.3E-2 arcminute or 0".78 angular size. Applying this to the comoving radial distance about 33.4 billion light years distant or 1.024048649E+10 pc, the galaxy size of 50,000 light years diameter close to 5E-3 arcminute angular size or close to 0.3 arcsecond size.
It is difficult to measure these sizes and distances
The comoving radial distances need to be reported to the public too and show what happens when factored in to the discussion about distances from Earth. Post #4 says, "Answer 1): With our modern telescopes we see 13.8 bn years age of the Universe. Since spacetime is expanding (stretching) the Universe is much bigger than 13.8 bn light years - having radius of 46 bn light years and diameter of 92 bn light years."
That radius of 46 billion light years is from earth and uses the comoving radial distance for the CMBR z = 1100. This is 4D space with hyperspace coordinate expanding faster than c velocity and if any galaxies are in that volume of space, very tiny sizes, none that can be observed and measured today from earth.
