Measuring Guidelines for Stainless Steel Countertops
and Copper Countertops

In This Section:

  • Select your mode of construction: Existing Countertops or New Construction
  • For wall squareness questions, see the 3-4-5 Rule
  • Measuring Diagonal corners or angles
  • Custom Metal Countertop & Sink Standards


  • Existing Countertops:
    Follow these measuring steps if you are replacing your existing countertops and your new tops will be the same shape and size. Referencing the sample drawing, record all measurements for each of your tops. You may print any sample drawing to assist you.

    Straight Tops

    1. Measure the total length along the back where the top meets the wall "A"
    2. Measure the total width along the side, from the wall to the front edge "B"
    3. Measure any existing sinks, left to right, front to back, and sink depth
    4. Measure any existing stove or sink cut outs left to right, front to back

    "L" Tops"
    1. Measure the total lengths along the backs where the top meets the walls "A" & "C"
    2. Measure the total width along the side, from the wall to the front edge "B" & "D"
      Note: It is important on tops with multiple sides, or "legs", to measure all sides for width, as they can be different to accommodate various cabinet depths.
    3. Measure any existing sinks, left to right, front to back, and sink depth
    4. Measure any existing stove or sink cut outs left to right, front to back

    Island Tops
    1. Measure the total length "A"
    2. Measure the total width "B"
    3. Measure any existing sinks, left to right, front to back, and sink depth
    4. Measure any existing stove or sink cut outs left to right, front to back


    Measuring Diagonal corners or angles
    Measure any key distances for special angles or corners. The diagram below is an example of a 45-degree inside corner.
    Measure A to E and C to F. Your measurement should be to the wall, including any backsplash depth.

    New Construction:
    Generally with new construction or full cabinet and countertop replacement, you will already have a drawing or layout from a designer, cabinet builder, or supplier. If not, sketch out the layout of your cabinets before beginning.
    Measure Cabinet Sections
    1. Measure the length of sectioned cabinets along your walls. "A"
    2. Measure the depth (front to back) on your cabinet sections "B".
    3. Measure your island cabinet section, both length and width "A & B"
    Note: As mentioned previously, cabinets are manufactured in various lengths and widths, so it is important to provide all cabinet measurements for your countertop.
    Utilizing industry standards, our countertops are manufactured with a 1" overhang at the front of cabinets to clear doors and drawers and any sides not butting into walls or equipment. Please indicate to us if your design style is different.


    3-4-5 Rule
    For new and replacement countertops, a key element is checking for wall squareness. This is essential to know if you will have a single countertop against two or more walls. Applying the 3-4-5 rule is the easiest method to determine if your walls are square, or 90 degrees. Mark your points lightly with a pencil or chalk and erase when finished.
    1. Measure a point on the first wall from the corner to three (3) feet out.
    2. Measure a point on the adjoining wall four (4) feet out.
    3. Measure the distance between the two new points - it should be five (5) feet, or 90 degrees.
    If the cross measurement is greater or less than five (5) feet, the wall is out of square. Don't fret, but please be sure to note this on your measurement submittals and we will discuss options with you based on how far the walls are out of square.


    Custom Stainless Steel Counter and Copper Counter Standards
    Custom Stainless Steel Sink and Copper Sink Standards
    :
    • Stainless counter and copper counter surfaces are 36" above the finished floor (A.F.F.)
    • Integrally welded stainless steel sinks and copper sinks are set back from the front edge a minimum of 2"-3", and 2"-3" from the rear backsplash to allow for faucet placement.
    • Stainless sink and copper sink drain openings are 3 ½" with a die depression to accept a crumb cup or flat drain.
    • Spacing between stainless steel countertops and copper countertops and upper cabinets is 15 to 18 inches.
    • Integral stainless steel backsplashes and copper backsplashes are formed 4" high with a 1" horizontal return towards the wall.
    • Wood substrate (wood backer) build up is 1 ½" for standard countertops.
    • Recommended sink minimum landing space is 24" on a dishwasher side and 18" elsewhere.
    • Stainless counter and copper counter island or bar countertop heights range from 28" to 45".
    • Drop-in range, stainless steel sink or copper sink units have an overlap flange of 3/8" to 1".
