the length of each shall be thirty cubits, and the width four cubits: all eleven sheets shall be of the same size.

See the chapter Copy

Likewise, the sheets of the tent will have an extra cubit’s length to be left hanging down on either side of the tabernacle to cover it.

The length of each shall be twenty-eight cubits, and the width four cubits; all the sheets shall be of the same size.

Also make sheets woven of goat hair for a tent over the tabernacle. Make eleven such sheets;

Join five of the sheets into one set, and the other six sheets into another set. Use the sixth sheet double at the front of the tent.
