Choose a mechanical keyboard layout by listing the keys you need within easy reach, then checking whether the exact enclosure leaves enough room for your mouse. Keep a numpad if your work depends on it. If you can give it up, compare the function row, arrows, and individual navigation keys before choosing a smaller layout.
This guide is for anyone moving from a familiar keyboard to a different size. It compares mechanical keyboard sizes, explains where a real 70% model fits beside 65% and 75%, and provides a worksheet for checking your daily tasks and desk space.
Quick takeaways
- Start with your applications and shortcuts.
- Check each required key on the exact regional layout diagram.
- Rehearse access to missing keys using the model’s own manual.
- Measure the enclosure and your mouse area separately.

Start with the keys you use
Mechanical keyboard size labels describe broad layout categories: which key groups remain and how they are arranged. They help narrow a search, but the exact diagram matters because manufacturers can retain different navigation keys or assign missing functions differently. Keychron’s comparison chart and KEMOVE’s size guide illustrate those differences.
Before comparing products, work through a normal task on your current keyboard. Record the keys you actually press, including commands used with Shift, Ctrl, Alt, or another modifier. Give each requirement a status: dedicated key required, combination acceptable, or unused.
| Key group | What to record | Question for the candidate keyboard |
|---|---|---|
| Numpad | Digits, decimal, arithmetic keys, and numpad Enter you use | Does the exact layout preserve the keypad arrangement you need? |
| Function row | Each F-key used alone or in a shortcut | Is that key physical, or must you add Fn? |
| Arrows | Cursor movement and selection tasks | Are all required arrows dedicated and placed where you expect? |
| Navigation and editing | Home, End, Page Up, Page Down, Insert, Delete, and any other required commands | Which individual keys remain, and how do you access the others? |
Avoid writing only “needs navigation.” A keyboard with arrows and Delete might still lack the dedicated Home or End key you want. Likewise, record the top number row and the separate numpad as different requirements; Keychron’s chart treats them as distinct groups. Source: Keychron.
Your completed list becomes the selection rule. If a candidate moves a required dedicated key onto a combination, either reconsider that requirement after a rehearsal or remove the candidate from your shortlist.
Mechanical keyboard sizes compared
The table below summarizes examples described by the linked sources. It is a starting point for inspecting a product, rather than a guarantee that every keyboard with the same label has an identical inventory.
| Layout example | Retained groups in the source example | Main selection check |
|---|---|---|
| Full-size | Numpad, function row, arrows, and editing keys | Confirm the familiar arrangement and measure its enclosure. |
| 96% compact numpad | Numpad, function row, arrows, and editing categories in Keychron’s chart | Inspect spacing and the exact navigation arrangement. |
| 1800-Compact | A numpad with arrows and navigation rearranged in KeyboardCo’s example | Check whether the relocated keys suit your habits. |
| TKL / 80% | Function, arrow, and editing groups without a numpad in Keychron’s chart | Confirm that giving up the numpad resolves your main space constraint. |
| 75% | Physical function row, arrows, and some editing keys | Check each navigation key you require. |
| 70% | Number row, arrows, some editing keys, and function keys through combinations in Keychron’s chart | Verify the model’s retained keys and function-key access. |
| 65% | Dedicated arrows and some navigation keys, without a separate function row in KEMOVE’s description | Check the navigation selection and F-key combinations. |
| 60% | An alphanumeric-focused arrangement, with missing groups accessed through combinations | Rehearse arrows, navigation, and F-key access. |

If you need a numpad
Compare full-size with compact numpad arrangements before dropping the keypad entirely. Keychron’s chart illustrates both full-size and 96% with the major functional categories retained. KeyboardCo’s 2017 guide describes an 1800-Compact example that places arrows below Enter and other navigation keys above the numpad. Sources: Keychron, KeyboardCo.
For a hypothetical spreadsheet user who wants to preserve keypad entry, those are sensible categories to inspect first. Compare the location of every required navigation key, then measure the candidate. The word “compact” alone does not tell you which groups are missing: Keychron’s compact 96% example still includes a numpad.
If you can give up the numpad
Use the function row as the next decision point. Keychron’s 80% and 75% examples retain physical function keys; its 70% and 65% examples use combinations. KeyboardCo describes 75% as reducing gaps and relocating navigation keys while retaining the F-row. Sources: Keychron, KeyboardCo.
If your requirements include dedicated F-keys, begin with TKL and 75% candidates. If combinations are acceptable, compare the exact 65% and 70% diagrams next. Consider a 60% candidate only after checking how its missing groups would work in your applications.
Where a real 70% keyboard fits
If you searched for “70 mechanical keyboard” or “mechanical keyboard 70,” the Keychron V7 provides a concrete example to investigate. The captured official Keychron V7 product specification identifies it as a QMK custom mechanical keyboard with a 70%, ANSI layout. The label is therefore a real manufacturer designation.
Keychron’s separate buying-guide chart illustrates 70% with 72 keys, arrows, some editing keys, no numpad, and function keys accessed through combinations. Its 75% example includes physical function keys, while its 65% row lists editing functions under combinations. Those are the chart’s examples; the chart does not establish the V7’s complete physical key inventory. Source: Keychron’s layout chart.
There is also a useful difference between sources. KEMOVE describes 65% as retaining a small navigation-key selection, whereas Keychron’s chart categorizes its 65% editing functions as combinations. That difference is a reason to inspect individual keys rather than assume every 65% keyboard omits them. Source: KEMOVE.
For your shortlist, ask whether a particular 70% model preserves a key that another candidate moves onto Fn. Then check its manual. Neither “70%” nor the chart’s illustrative count supplies a universal cross-brand key map.
Rehearse missing-key access
A missing dedicated key can still have an assigned function through Fn combinations. KeyboardCo’s 60% discussion explains this approach and explicitly warns that assignments vary by manufacturer and model. Use the selected keyboard’s documentation for actual shortcuts. Source: KeyboardCo.
Run this rehearsal before accepting a smaller layout:
- Choose a representative task. Use a document, spreadsheet, editor, or game you already know.
- List its required commands. Include combinations involving F-keys, arrows, and navigation keys.
- Find each command in the candidate’s manual. Record the physical key or documented combination.
- Check the full hand movement. Include Fn and any modifiers your application requires together.
- Identify unresolved commands. Keep the candidate under consideration only when every required command has an acceptable documented route.
Without the keyboard in hand, this is a planning exercise. It can reveal an awkward proposed combination, but it cannot establish how comfortable or fast the layout will feel.
For example, imagine that your checklist requires arrows and Home/End, while F-keys are occasional. A 65% or 70% candidate is worth inspecting, provided its exact key map passes those requirements. If the same checklist marks dedicated F-keys as mandatory, return to the 75% or TKL candidates instead. These are conditional selection examples, not measured performance results.
Measure the enclosure and mouse area
Use a product’s enclosure dimensions for desk planning. For the V7, Keychron’s captured specification labels width as 117 mm and length as 341.85 mm. Preserve those field names when recording the specification, and confirm the orientation against the product drawing. They describe this model, not every 70% keyboard. Source: Keychron V7.
Use this worksheet beside your key requirements:
| Measurement | What to record | How to check it |
|---|---|---|
| Candidate enclosure | Manufacturer dimensions and their labeled orientation | Compare them with the exact model’s drawing. |
| Keyboard position | Where you want the typing area on the desk | Mark the proposed enclosure boundary with removable tape. |
| Mouse movement area | The space you use during representative tasks | Move the mouse normally beside the marked boundary. |
| Surrounding clearance | Space needed around nearby equipment and any cable exit | Inspect the proposed setup for conflicts. |
For a V7 planning example, mark a 341.85 mm × 117 mm rectangle and confirm which edge runs across the desk. Position it where you would actually type, then rehearse your usual mouse movement beside it. This checks the proposed arrangement without assuming that the percentage label predicts its dimensions.
If the enclosure fits but the key checklist fails, keep looking. If the keys work but the marked boundary crowds your mouse movement, compare another enclosure or layout arrangement.
Check regional layout and replacement keycaps
Verify the exact regional variant before settling on a size. KeyboardCo’s full-size discussion distinguishes ANSI, ISO, and JIS examples, while the captured V7 specification specifically identifies ANSI. A percentage label is insufficient to establish the regional key map. Sources: KeyboardCo, Keychron V7.
If replacement keycaps matter to you, ask the supplier to compare the proposed set with that exact diagram. KeyboardCo warns that replacement caps can be harder to find for its described 75% arrangements. Source: KeyboardCo.
Ask whether the set covers every required key width, position, and legend. Request confirmation of row-profile coverage and documented stem and stabilizer fit. These are compatibility questions to resolve for the particular keyboard and set; this guide does not certify a replacement kit.
Frequently asked questions
Does “compact” mean a keyboard has no numpad?
No. Keychron’s comparison chart includes a compact 96% arrangement with a numpad, and KeyboardCo describes an 1800-Compact arrangement that retains one. Treat “compact” as a prompt to inspect the layout. Check the actual key groups and enclosure dimensions before deciding whether it meets your requirements. Sources: Keychron, KeyboardCo.
Is a mini mechanical keyboard the right choice for a small desk?
Choose it only if its documented key access and measured enclosure fit your setup. Start with the keys you require, then check the model’s dimensions and mouse clearance. For example, Keychron supplies specific dimensions for the V7; its 70% label alone does not replace that measurement check. Source: Keychron V7.
Can one Fn shortcut guide cover every 60% keyboard?
No. KeyboardCo explicitly describes variation between manufacturers and models. Check the manual for the exact keyboard, including the full combinations your applications require. A general layout guide can explain why Fn access matters, but it cannot establish the assignments on an uninspected model. Source: KeyboardCo.
Choose the layout that passes both checks
The useful comparison between mechanical keyboard sizes has two parts: acceptable access to your required keys and enough physical space for your setup. Preserve dedicated keys where your checklist demands them, and accept combinations only after checking the exact manual.
Your next step is to open a candidate’s regional layout diagram and dimensions, then complete the key and desk worksheets. Use those results to narrow your search to the layout that fits your work.
