Why Word Size Carries Meaning
A word cloud turns importance into size. The most important word is the biggest, the next is smaller, and so on, so the eye finds the main idea first and the details second. That is the whole value of the format, and it is also its main risk: if the sizes do not reflect real importance, the cloud lies. The tool above sizes words by the weights you give them, packs them into a cloud on a canvas using wordcloud2.js when available, with a native canvas fallback, and lets you download the result as a PNG.
The input is a simple list, one word per line, with a weight after a colon, such as design: 90. Weights are relative, not absolute: a word at 90 is twice as prominent as a word at 45, and the tool scales all words to fit the canvas together. Keep the list honest. If every word gets a weight of 90, the cloud has no hierarchy, and it becomes decoration instead of information.
How to Use the Maker
Type or paste your words, one per line, in the format word: weight. Use weights between about 10 and 100, with a clear gap between the most important words and the rest. A list where the top word is 90 and the rest cluster around 30 reads clearly. A list where every word sits between 70 and 90 reads as a blob. Then press Make cloud. The tool packs the words, rotating some for a natural cloud feel, and shows the result on the canvas. Press Download PNG when you like it.
If a word is missing or tiny, check its weight and its spelling. Multi-word phrases need care: wordcloud2 treats each line as one entry, so a phrase stays together, but very long phrases may not fit and can be dropped or shrunk. Prefer single words or short two-word phrases, and keep the total list to ten to twenty entries for readability.
Designing Clouds That Communicate
A good cloud has a clear winner. One word should dominate, two or three should support it, and the rest should fill the space. That hierarchy mirrors how people read: headline, subheads, detail. If two words tie for the top size, the eye does not know where to start, so break ties by adjusting weights by ten points or more. Small differences of two or three points are invisible, so make weight differences decisive.
Colour is secondary to size. This tool uses dark random colours, which keep the focus on size rather than hue. If you recolour the cloud for a presentation, keep the biggest words darkest, because dark and large together signal importance twice. Avoid giving a minor word a loud colour, which would fight the size hierarchy and confuse the reading order.
Where Word Clouds Work and Where They Do Not
Word clouds suit presentations, posters, and social posts, where the goal is a quick impression of a theme: the words of a survey, the themes of a book, or the values of a team. They suit brainstorming walls, where the cloud itself invites discussion about what matters most. They do not suit precise data, because readers cannot recover exact values from font sizes. If exact numbers matter, use a bar chart instead, and use the cloud only as a decorative companion.
They also do not suit long lists. Beyond about thirty words, the small words become unreadable, and the cloud turns into texture. Trim ruthlessly: if a word would not change a reader’s understanding, cut it. A cloud of twelve meaningful words beats a cloud of fifty forgettable ones.
Frequently Asked Questions
Why is my biggest word not much bigger? Because the weights are too close together. Widen the gap: set the top word to 90 and the supporting words to 40 or below, and the hierarchy will appear.
Can I use phrases with spaces? Yes, one phrase per line. Keep phrases short, or they may shrink or drop out when the packer runs out of space.
What if wordcloud2.js does not load? The tool falls back to a native canvas layout that places words in a spiral with sizes from your weights, so you still get a real cloud.
