Architectural Dimensioning
Part 1
Floor-Plan DimensionsFloor-Plan Dimensions
Dimensioning systemAligned dimensioning--dimensions are placed in line
with the dimension lines and are read from the bottom or right side of the drawing sheet
Dimension lines are solid (Thin) and not brokenDimensions are placed above dimension lines
approximately 1/16” above line
Example of Aligned
Dimensioning
Example of Aligned
Dimensioning
Note:Dimensions readable from the bottom of sheet and right side of sheet above the dimension line
Writing the Actual Dimension
Writing the Actual Dimension
Feet and Inch/fractions: 6’-7 1/2”Even feet no inches: 4’- 0”Feet and zero inches/fractions: 8’- 0 3/4”No feet only inches: 10”No feet only inches/fractions: 5 1/2”Only fractions of an inch: 3/4”
General Rules to Follow for Placing Dimensions
General Rules to Follow for Placing Dimensions
Place exterior dimensions outside the floor plan, starting with the smallest first, then subtotals and finally overall totals
Place interior dimensions inside the floor plan in string fashion. Several strings may be required both horizontally and vertically
Arrows or TerminatorsArrows or TerminatorsFor class project use diagonal lines for all
dimensioning terminatorsUse arrows for all leaders and callouts
Making Arrows for LeadersMaking Arrows for Leaders
Arrows for dimensions and leader lines should be the same
Arrows usually have a set proportion and have a slender look to them
1/8” to 3/16”
1/32” to 1/16”
Making Tick Marks for Terminators
Making Tick Marks for Terminators
Commonly 1/8” long at 45 degree Usually done freehand
Freehand slash all in the same
direction
A thick slash is common on manual and CADD
drawings
Dimension ProceduresDimension Procedures
Dimensions are placed on the drawing are dependant upon the type of material the walls are constructed of:
1) Frame or wood studs2) Brick or stone veneer over frame3) Solid masonry and cast concrete
Discussion today include 1 and 2
Frame or Wood Studs Walls
Frame or Wood Studs Walls
Two x 4 or 2 x 6 make up the Skeleton of the structure
A common wood frame wall is 5 1/4” thick
This wall is drafted 6”
Frame or Wood Studs Walls
Frame or Wood Studs Walls
To communicate to the carpenter this exterior wall is dimensioned to the outside face of stud
This dimension is 1 1/4” from the outside line of the wall
Frame or Wood Studs

Frame or Wood Studs
Walls
Materials terms that make up the wood frame wall:
Siding (3/4”)Sheathing (1/2”)Stud (2x4)Gypsum Board (1/2”)Insulation in stud wall
Spacing of Dimensioning Lines
Spacing of Dimensioning Lines
First string of dimensions are usually placed about 3/8” to 1” from the object depending upon the amount of space available
Second string of dimensions are placed 3/8” to 1/2” from the first string of dimensions
Additional strings of dimensions are spaced like the second string of dimensions
Dimensioning Exterior Frame or Wood Stud Walls
Dimensioning Exterior Frame or Wood Stud WallsDimension to the outside face of studDimension to centers of doors and windowsDo not dimension interior partitions with the
exterior string of dimensions
Steps in Dimensioning a
Plan
Steps in Dimensioning a
Plan
Step #1--Place extension lines at face of exterior studs, center lines at centers of doors and windows
Place first string of dimension lines about 3/4” away from floor plan

Step #2--Place second string of dimensions about 1/2” from first string
These dimensions are considered to be subtotals

Step #3--Place overall dimension line about 1/2” away from previous dimension line
Check that all cumulative dimension equal the subtotal dimensions
Brick or Stone
Veneer over Frame
Brick or Stone
Veneer over FrameSame skeleton as framed structure but stone or brick replaces the siding with air space between brick and sheathing
Dimensioned to face of stud
Brick or Stone Veneer over Frame
Brick or Stone Veneer over FrameDimension to the outside face of stud
Dimension to centers of doors and windowsDo not dimension interior partitions with the
exterior string of dimensions
Read Instructions & Follow all rules that apply:
#1--Dimension exterior horizontal dimensions
#2--Dimension exterior vertical dimensions

Dimensioning StepsDimensioning StepsTape drawing to drafting table and square with
drafting machine.All work at this point will be with a 4H pencil (very
thin): .3mm or .5mm with hard lead
Dimensioning StepsDimensioning StepsPlace Extension linesPlace Extension lines at measuring points of the
plan: 1)Face of stud of wood wall (1 ¼”) from outside wall line, 2)Face of stud of Veneer wall (5 ¼” from outside wall line, 3)Center of door and window
Add Extension lines
Center Line
Dimensioning StepsDimensioning Steps
Place first line of dimension from plan (3/8” to 1”)
3/8” to 1” from plan
Dimensioning StepsDimensioning Steps
Add sub total and total dimension lines. Note some plans will not require sub total dimension lines
3/8” to ½” ” from previous line
Dimensioning StepsDimensioning StepsClean up extension lines and dimension lines and
add any final dimension lines: (thickness of brick to face of stud, do only once and write (TYP) meaning TYPICAL
Label at one location (TO FACE OF STUD) with leader pointing to it.
To Face of Stud5 ¼”(TYP)
Dimensioning StepsDimensioning StepsAdd tick marks at all intersections of extension lines and
dimension lines.Add guidelines above dimension lines and place values
of measurements between tick marks
Add Tick Marks
Add Dimens
