A toilet's drain must be run at 1/4 per foot minimum grade when horizontal. A toilet cannot be installed upstream of any wet vented fixture. The maximum vertical fall of the drain is 1 meter(39 inches) and the maximum horizontal run is 3 meters before it connects to a vent. All downstream drainage after the connection of a third toilet on the same horizontal pipe must be 4 diameter or larger.
A bathroom sink drain hole is typically 1.25 inches in diameter. While a bathroom sink's design and overall size may vary from one model to the next, the drain holes are fairly standard, 1.25 inches being a general standard, with widths of 1.5 inches and 1.625 inches also common. The size of the hole helps determine which size drain is needed for that particular sink.
