Charles Ellicott Commentary Ezekiel 41:11

"And the doors of the side-chambers were toward [the place] that was left, one door toward the north, and another door toward the south: and the breadth of the place that was left was five cubits round about." — Ezekiel 41:11 (ASV)

The doors of the side chambers.— These doors opened onto the platform; the door for the north-side series opened to the north, and the one for the south-side series opened to the south. There was only one door on each side, so the series of chambers must have been entered one from the next.

We can now summarize the measurements of the Temple with its chambers and surrounding space. The components were: the wall, 6 cubits; the chambers, 4; their outer wall, 5; the platform beyond, 5; and the space beyond this, 20 (totaling 6 + 4 + 5 + 5 + 20 = 40 cubits). This measurement applied to each side, so it is doubled, making 80 cubits. To this, add the 20 cubits of the Temple's inner width, and we have exactly 100 cubits, which is the width of the inner court.

The length is calculated similarly. Here, the porch is considered to belong to the court, along with the front wall of the Temple (its thickness is included in the length of the porch). Beginning from the inside of the outer walls, the measurements are: the inner length of the Temple, 60 cubits; the rear wall, 6; the chambers, 4; the outer wall, 5; the platform, 5; and the space, 20; totaling 100 cubits. This results in an exact square.
