1. SILL HEIGHT (S.H.) MEASURE FROM THE FLOOR TO THE BOTTOM OF THE SASH (USUALLY ABOUT HALF WAY UP THE WINDOW STOOL. SEE SECTION "B" )
UNIT HEIGHT (U.H.) MEASURE FROM BOTTOM OF SASH TO TOP OF UPPER MOST SASH
THE ABOVE CAN BE PLUS OR MINUS ½" WITHOUT ANY ADVERSE CONSEQUENCES.

2. WIDTH OF WINDOW SASH. I USUALLY MEASURE FROM OUTSIDE THE STOP ON ONE SIDE TO OUTSIDE THE STOP ON THE OTHER. (SEE SECTION "A" )

3 DOOR WIDTH. THE EASIEST THING TO DO IS MEASURE THE DOOR ITSELF.

4. C.H. IS THE CEILING HEIGHT

5. THE DASHED LINE REPRESENTS THE BREAK OR BEND IN THE CEILING AS SHOWN IN THE CROSS SECTION BELOW. I ALSO SHOWED IT NOT ALIGNING. THIS HAPPENS. THESE DON'T NEED TO BE FINISHED DRAWINGS AND IF SOMETHING COMES OUT ASKEW MAKE NOTES AND CARRY ON.

6. MEASURE BOTH SIDES OF A WALL EVEN IF YOU ARE SURE THEY ARE THE SAME. PANELING AND OTHER ITEMS MAY VARY THE MEASUREMENTS. AS MUCH AS POSSIBLE MEASURE TO THE PLASTER OR SHEETROCK WALLS. DISCOUNT THE MOLDINGS AROUND WINDOWS AND DOORS. PRETEND YOU ARE MEASURING THE HOUSE BEFORE IT WAS TILED OR TRIMMED.

7. MEASURE NEGATIVE SPACE WHEREVER APPROPRIATE. ALSO OVERALL ROOM MEASUREMENTS ARE USEFUL AS CHECK NUMBERS.

8. LOOK FOR ANY SIGNS OF STRUCTURAL MEMBERS AND NOTE ACCORDINGLY.

9. NOTE ADJACENT ROOMS OR "OVERLAP" DRAWINGS SO IT IS CLEAR WHICH MEASUREMENT SHEET GOES WITH WHICH.

10. MEASURE AND RECORD STAIRS AS SHOWN.

11. THIS "SCRAP SECTION" RELATES TO NUMBER 5 ABOVE. IT SHOWS THE PITCH OF THE CEILING AND CAN BE HELPFUL IN ESTABLISHING THE ROOF PITCH.

12. THE EXPOSURE REFERRED TO IS THE EXTERIOR SIDING. I USUALLY MEASURE 10 COURSES AND THEN DIVIDED BY THAT NUMBER TO GET AN AVERAGE.

REMEMBER IT'S ALMOST IMPOSSIBLE TO HAVE TOO MUCH INFORMATION.
