I'm going to be tiling a bathroom with 1 1/8 in. subfloor which will meet up with carpet. Would like to use 1/2 in hardy concrete board, but looks too high next to carpet. Will 1/4 board be enough for 13" ceramic tiles?

1/4" will be fine since the cement board does not offer any structural support like plywood, but it does offer the best surface to set tile on. If your subfloor is made up of only layers of plywood or OSB you should be good to go.

When setting the hardibacker, put it in a bed of thinset combed evenly with a 1/4" square notch trowel. The thinset in this instance is there to fill in voids between the CBU and the plywood under it. By eliminating the voids you get rid of any compression of the board which could cause the tile to crack or come loose. Use galvanized 1 & 1/4" roofing nails or backerboard screws to actually anchor the board to the subfloor. Tape the seams with mesh tape and a thin even coat of modified thinset. For that size tile I would recommend a 3/8" deep by 1/4" wide square notch trowel. Use a good modified thinset to set the tile, comes in a bag, you mix with water.
