Proportion

The governing concept is anatomical proportion: connected parts must have believable size relationships. If the head is drawn at a suitable size but the neck is made extremely thin, the mismatch occurs between the head and neck. Colour, background, lighting, and texture may affect other qualities, but none explains this structural error. Hence option C correctly identifies the unbalanced relationship.

The governing concept is comparative proportion: an object is judged in relation to another object, not in isolation. The artist can compare the bottle’s height with the glass’s height and also check their relative widths. This establishes whether the drawn sizes correspond to the observed arrangement. Colour counting and shadow inspection do not measure size relationships, and paper length is unrelated. Therefore, option B is correct.

The governing concept is ratio in proportion. Let the height be 2 equal units; because the width is half the height, the width is 1 unit. Writing the requested relationship in the stated order, width:height = 1:2. Therefore option B is correct. Option A means equal dimensions, option C reverses the relationship, and option D represents a different ratio.

The governing concept is simplifying a proportion by dividing both terms by their greatest common factor. For width:height, the ratio is 8:12. The greatest common factor of 8 and 12 is 4, so 8 ÷ 4 : 12 ÷ 4 = 2:3. Option C is therefore correct. Option D is equivalent but not simplified, while A and B do not preserve the required reduced relationship.

The governing concept is a scale factor applied to a proportionally enlarged figure. The original width is 5 centimetres and the enlargement factor is 3, so new width = 5 × 3 = 15 centimetres. Therefore option D is correct. The other values result from adding, doubling, or using an unrelated multiplier rather than applying the stated factor consistently.

A good sketch depends first on accurate form: the object should have a clear outline and proportionate relationships between its parts. Correct proportion means that the relative width, height, and size of details look believable. Therefore option B is correct. Many colors, dark lines, or a large sheet may be choices of presentation, but none guarantees an accurate sketch.

Comparing width with height establishes the object’s proportion, or the relationship between its main dimensions. For example, if an object is twice as high as it is wide, the sketch should preserve that relationship instead of using unrelated measurements. Thus option A is correct. Coloring, erasing, and decorating may occur later, but they are not the purpose of comparing dimensions.

A common basic proportion for a front-facing head is that the gap between the two eyes is approximately one eye width. Artists use this as a starting measurement, then adjust it after observing the actual subject, viewpoint, and expression. Option C is correct. A half-eye gap is usually too narrow, while two or three eye widths would make the eyes unnaturally far apart in a standard face construction.

The governing concept is proportion, which describes the relationship between dimensions or parts of an object and between objects in the same drawing. Comparing height with width helps the artist maintain believable forms and relationships, so option A is correct. Texture describes surface quality, hue identifies a colour family, and rhythm concerns visual repetition or movement rather than measurement.

Proportion is the measured relationship between the parts of an object or composition. When drawing, comparing an object’s height with its width helps preserve its recognizable shape and prevents it from appearing stretched or compressed. Therefore, option B is correct. Texture describes surface quality, hue identifies a colour family, and rhythm refers to repeated visual movement; none of these terms describes the height-to-width relationship.

The governing concept is proportion, specifically the relationship between parts within one object. The vase neck must be measured in relation to the width and height of the body; if it is too wide or too narrow, the object’s structure and visual likeness are altered. Therefore B, internal proportion, is correct. Texture, light direction, and background value are separate concerns and are not changed by the neck’s width.

In the grid method, matching grids are drawn on the reference image and the drawing surface. Copying one square at a time helps maintain the position, size, and proportions of shapes accurately. Mixing colours is a colour-theory process, not a purpose of the grid method. Exam tip: Remember that grids are especially useful for enlarging or reducing an image while keeping its proportions correct.

Proportion in art means the relationship of size, length or amount between parts of an object or between elements in a composition. Correct proportion can make a figure or design appear coherent and believable, so option A is correct. Colour contrast, texture and line direction are separate visual concerns. They may influence the artwork, but none of them alone defines proportion.
