List the keys that your work needs
Compact keyboards remove or rearrange keys in different ways. Some omit only the number pad, while others move navigation and function keys onto secondary layers. Percentage labels are approximate descriptions, not complete layouts. Inspect a clear diagram and identify the keys you use every day before comparing case dimensions.
For writing, that may mean Delete, Home and End. For spreadsheets, a number pad can be important. For software work, function keys and punctuation may matter more. A smaller board can bring the mouse closer, but that benefit should be weighed against the extra combinations required for ordinary actions. The tradeoff differs between users.
Test a real sequence
Type a paragraph, edit a line, switch applications and use your usual shortcuts. Try the sequence at a normal pace rather than carefully hunting for each symbol. This reveals whether a function layer is easy to remember or interrupts the task. Check how the keyboard indicates an active layer or lock state, especially if several people will use it.
If remapping is supported, find out whether the setting is stored on the keyboard or depends on software running on the computer. A configuration that works at home may not be available on a managed work device. Do not assume you can install a utility wherever the keyboard travels. Keep the default layout usable enough for recovery and unfamiliar computers.
Measure the complete desk arrangement
Place the keyboard where it will actually be used and leave room for the mouse movement your work requires. A compact board may be useful even on a large desk if it changes the reach to the mouse. Conversely, a very small travel keyboard can be less pleasant for long stationary sessions. Portability and desk comfort are related but separate questions.
Check the physical language layout, connection method and charging or battery arrangement. A detachable cable should not block another device in a crowded travel setup. If a separate number pad is planned, include its footprint and cost. The useful outcome is a smaller arrangement that preserves fluent work, rather than a reduced key count that must be compensated for at every step.
