Keep a Thumbnail Aspect Ratio - Practice 1

5 questions0m 0s

Learn the skill

An aspect ratio compares width to height. For a 2:3 portrait rectangle, each two width units correspond to three height units. Use equivalent ratios rather than adding the same amount to both dimensions.

Worked example

At ratio 2:3, width 8 cm corresponds to height 12 cm.

A portrait rectangle with ratio two to three is enlarged to four to six. Both width and height double, preserving proportion. Labeled values define the plan; screen resizing changes physical ruler measurements.

Question 2 Portrait thumbnail 2 has width:height ratio 2:3 and width 6 cm. What height in cm preserves the ratio? Answer

Question 3 Portrait thumbnail 3 has width:height ratio 2:3 and width 8 cm. What height in cm preserves the ratio? Answer

Question 4 Portrait thumbnail 4 has width:height ratio 2:3 and width 10 cm. What height in cm preserves the ratio? Answer

Question 5 Portrait thumbnail 5 has width:height ratio 2:3 and width 12 cm. What height in cm preserves the ratio? Answer

Make It Your Own

Optional theme: a surprising delivery. Plan three thumbnails within the same 2:3 frame, changing the arrangement inside each. Choose one and explain how its empty space and focal area work. You may draw, write or tell your idea. Use invented characters and places; no personal information or upload is needed. This activity is not scored.

Reflect on your choices

Keep the frame proportions while varying the internal composition.
Explain one intentional choice and one possible alternative.
