What is a basic sleeve
The basic set-in sleeve pattern is one of the most important sewing patterns for dressmaking. You may add pleats, folds, flounces, or gathers to the sleeve and create endless variations of an otherwise very simple and basic design. For a detailed look at the individual sleeve parts, including how to distinguish front and back and understand their roles in a basic sleeve, see the Sleeve Construction Basics overview.
Draft your own bodice with this beginner-friendly Basic Bodice Pattern Tutorial. No math, no confusion. A clear, step-by-step approach.
Tools and measurements you will need
Tools: Large sheet of paper or tissue paper, pencil, thin marker (Sharpie), long ruler, French curve.
Pattern base: The bodice you are drafting the sleeve for (it should NOT be designed as a sleeveless).
Measurements: Bodice armscye FRONT length, armsyce BACK length, arm length, upper arm circumference and wrist circumference.

How to draft the basic sleeve pattern step-by-step
Draw grey lines in pencil as guidelines, and black lines with a Sharpie as the pattern lines. Iron the tissue paper if needed and avoid using creased or crumpled paper.
On the prepared sheet of paper draw a long vertical line.
At the top of the paper, draw a small marking called shoulder. At the bottom mark the wrist. The distance between the two is your measured arm/sleeve length.
a = measured arm length
Draw a marking for the upper arm line – this is the cap height, you have measured as the distance from the tip of your shoulder to the armpit line.
b = cap height
Draw the upper arm (biceps) line and the wrist (hem) line.
On the upper arm line, mark the underarm seams. The distance between the shoulder and the underarm marking is calculated according to the following formula:
c = (bodice FRONT armscye + bodice BACK armscye)/2
d = (bodice FRONT armscye + bodice BACK armscye)/2
Connect the shoulder and underarm seam markings. These two diagonal lines are the base for drawing the basic set-in sleeve cap.
Now, measure the distance between the two underarm seams. It should be larger, than the circumference of your biceps.
Divide both diagonal lines you have drawn in the previous step into quarters. Each quarter has the same length (in this tutorial labeled as e). Mark A, B, C, D, E and F.
e = (diagonal line length)/4
From the diagonal lines, square out* short lines towards the outside or inside of the diagonal lines. You will use them to draw the sleeve cap.
Use the following measurements:
A (inside): 1 cm (3/8″)
B (outside): 0,5 cm (1/4″)
C (outside): 1,5 cm (5/8″)
D (outside): 1,8 cm (3/4″)
E (outside): 0,8 cm (5/16″)
F (inside): 1,3 cm (1/2″)
* To square out the small lines means to draw them at a right angle (perpendicular) to the diagonal line.
Using a French curve, draw the shaped sleeve cap by passing the tips of the short lines. Make sure not to cross the short lines. It may take a minute or two to find the proper portion and position of the French curve, so be patient :).
On the wrist line, mark the underarm seam.
f =
sleeve width/2 – 2”
g =
sleeve width/2 – 2”
f =
sleeve width/2 – 5 cm
g =
sleeve width/2 – 5 cm
Using a long ruler, draw the wrist and underarm seams.
On the BACK part of the sleeve cap, mark the length of the bodice BACK armscye. On the FRONT of the cap, mark the bodice FRONT armscye length.
To do so: use a tape measure, measure the bodice armscyes, and transfer the measurements. Alternatively, you can walk the bodice pattern along the sleeve pattern.
h = bodice BACK armscye length
i = bodice FRONT armscye length
Measure the distance between the armscye markings. This distance is the ease of the sleeve cap.
In the middle of the measured sleeve cap ease, mark the CENTRE notch. This notch may not be aligned with the central vertical line you have drawn at the beginning. This does NOT mean, that you have drafted the sleeve incorrectly.
On the sleeve cap at the BACK, mark 1/3 of the bodice BACK armscye length. Drawing two short lines, you will mark the BACK notch for the sleeve.
On the sleeve cap at the FRONT, mark 1/3 of the bodice FRONT armscye length. Drawing one short line, you will mark the FRONT notch for the sleeve.
j = (bodice BACK armscye length)/3
k = (bodice FRONT armscye length)/3
The sleeve pattern is finished. Now, you can sew and test it with your bodice.
How to use the pattern?
Sew it and test with the bodice you drafted the pattern for and see how it fits. Apart from using the pattern you have drafted in this tutorial, you can further modify it to make other types of sleeves and sleeve designs.

- Arm circumference: at bicep, elbow, and wrist.
- Shoulder slope and shoulder width.
- Armscye circumference: the opening where the sleeve attaches to the bodice.
