How to Draw Glass — Free Practice Sheets

Drawing a glass is mostly a problem of shape and proportion. A drinking glass has a few visible features that make it readable: an open elliptical rim, sides that taper slightly toward the base, a flat bottom, and a thick lower edge. This page explains how to build those features in order, how to use the practice sheet formats, and how to assess your drawing fairly when more than one result can be correct.

Start with the rim and sides

Begin with the open rim. Because the glass is seen from slightly above or at eye level, the rim appears as an ellipse rather than a straight line. Keep the ellipse wide enough to suggest an opening, and place it near the top of your page so the body has room below.

From the rim, draw two vertical lines downward. They should converge slightly toward the base, because many glasses narrow a little at the bottom. Keep the two sides balanced; if one leans, the glass will look tilted. These lines define the silhouette before any detail is added.

1. Draw a vertical ellipse for the open rim.
2. Draw two slightly converging vertical lines down from the rim to form the sides.
3. Draw a curved line connecting the bottom of the sides to form the base.
4. Add a second curved line near the bottom to indicate the thick glass base.

Close the base and show the thick edge

Connect the bottom of the two sides with a curved line. The curve should echo the rim's ellipse but be shallower, since the base is usually less open than the top. This line marks the outer bottom of the glass.

Add a second curved line just above the base to show the thick glass bottom. The gap between the two curves represents the visible thickness of the glass. Keep that gap consistent across the width of the base; an uneven gap makes the bottom look warped rather than solid.

1. Check that both side lines meet the base curve cleanly.
2. Draw the inner base curve parallel in feel to the outer one.
3. Compare the rim width and base width before adding any extra marks.

Using the practice sheet formats

The trace sheet asks you to follow the reference outline first, then practise the contour independently. Use the trace pass to learn where the rim, sides, and base sit, then cover or set aside the outline and redraw from memory. Compare your independent drawing with the separate full reference sheet.

The grid sheet asks you to copy the reference onto a blank grid using matching grid intersections. Place the rim, the side lines, and the base at the same intersections as the reference. The bounding-frame sheet gives you a frame and center guide to place the silhouette before adding identifying details. The partial sheet gives you the left portion and asks you to complete the blank right-hand portion from the full reference. In every format, compare with the separate full reference sheet rather than expecting a pixel-perfect match.

1. Identify the rim, sides, base, and thick bottom edge in the reference.
2. Place those four features first, then refine the curves.
3. Compare your drawing with the full reference and note one proportion to adjust.

Judging the result

A glass drawing can be correct in more than one way. Slight changes in taper, rim openness, or base thickness are valid choices. Assess the visible features and proportions instead of demanding an exact copy. Ask whether the rim reads as an opening, whether the sides taper consistently, and whether the base looks flat and thick.

1. Check the rim ellipse for a clear opening.
2. Check that the sides converge slightly and stay balanced.
3. Check that the base is flat with a visible thick edge.

Worked example

Prompt: Trace the reference outline, then practise the contour independently. Compare with the separate full reference sheet.

Example solution: preserve cylindrical sides tapering slightly toward the base, open elliptical rim at the top, flat base with a thick bottom edge. Other drawings can be correct; assess the visible features and proportions rather than pixel-perfect matching.

1. Draw the rim ellipse.
2. Add the two slightly converging sides.
3. Close the base with a curve.
4. Add the inner curve for the thick bottom edge.

Check your work

• The rim is drawn as an ellipse that reads as an opening.
• The two sides taper slightly toward the base and remain balanced.
• The base is closed with a curve and shows a second curve for thickness.
• The rim, body, and base proportions are consistent with the reference.
• The drawing is assessed by visible features rather than exact copying.

Common mistakes

• Drawing the rim as a flat line instead of an ellipse. Curve the rim so it reads as an opening seen at a slight angle.
• Making the two sides parallel or unevenly slanted. Taper both sides slightly toward the base and keep them balanced.
• Leaving the base as a single line with no thickness. Add a second curve above the base to show the thick glass bottom.
