Most kitchen cabinets follow a small set of standard dimensions: 600 mm deep base units, a 900 mm counter, 300–350 mm deep wall units and 2,100–2,400 mm tall units. The errors that cost money are not wrong numbers but wrong reference points: measuring from the wall instead of the finished face, or forgetting the door and counter thickness. Agree the reference point before you measure.
Base cabinets are 600 mm deep, 720 mm carcass, 900 mm with counter.
Wall cabinets are 300–350 mm deep and 600–900 mm high.
Tall cabinets run 2,100–2,400 mm high and 600 mm deep.
Allow 450–600 mm between counter and wall cabinet.
Measure from the finished face, not the bare wall.
1. The three cabinet types
Every kitchen is built from three boxes: base, wall and tall. The dimensions below are the common starting point, not a rule. A project that follows them will fit standard appliances and counters; a project that departs from them needs a reason and a drawing.
2. Base cabinet dimensions
| الابعاد | متري | إمبراطوري | ملاحظات |
|---|---|---|---|
| عمق | سماكة 600 ملم | 24 في | Includes door |
| Carcass height | سماكة 720 ملم | 28 في | Excludes counter |
| ارتفاع المنضدة | سماكة 900 ملم | 36 في | Counter top surface |
| عرض | 300 – 900 مم | 12–36 بوصة | 600 mm most common |
| ركلة إصبع القدم | 100 – 150 مم | 4–6 بوصة | Set back 50–75 mm |
The carcass height plus counter thickness equals the counter height. If the counter is 20 mm stone, the carcass is 880 mm to reach 900. That arithmetic is where most height errors start.
3. Wall cabinet dimensions
| الابعاد | متري | إمبراطوري | ملاحظات |
|---|---|---|---|
| عمق | 300 – 350 مم | 12–14 بوصة | 350 mm for plates |
| الطول | 600 – 900 مم | 24–36 بوصة | 900 مم مشترك |
| فوق المنضدة | 450 – 600 مم | 18–24 بوصة | To cabinet bottom |
| عرض | 300 – 1,000 مم | 12–40 بوصة | Double door above 600 |
| Top to ceiling | 0 – 600 مم | 0–24 بوصة | Bulkhead if over 300 |
Wall cabinet height is usually decided by ceiling height and whether a bulkhead is acceptable. A 900 mm cabinet with a 450 mm gap and a 2,400 mm ceiling leaves 1,050 mm above the cabinet, which usually needs a bulkhead or a second row.
4. Tall cabinet dimensions
Tall cabinets run 2,100–2,400 mm high and 600 mm deep, with widths from 300–900 mm. They house ovens, fridge housings and larder storage. The height is usually set by the ceiling and the appliance stack, not by a standard. Confirm the appliance dimensions before fixing the tall height, because a 5 mm error at the top is visible.
5. Depth, fillers and clearances
Fillers close the gap between the cabinet run and the wall. Allow 50–150 mm at each end, more if the wall is out of square. A 150 mm filler is normal; 300 mm usually means a design error or a wall that needs packing. The دليل التخليص covers appliance gaps and door swing.
6. Metric and imperial
| العناصر | متري | إمبراطوري |
|---|---|---|
| عمق القاعدة | سماكة 600 ملم | 24 في |
| ارتفاع المنضدة | سماكة 900 ملم | 36 في |
| عمق الجدار | سماكة 350 ملم | 14 في |
| Wall gap | سماكة 500 ملم | 20 في |
| ارتفاع طويل | سماكة 2,400 ملم | 94 في |
The conversions are close but not exact. Pick one system for the drawing and note the other for reference. Mixing them in one schedule is how 36 in becomes 914 mm and a 900 mm gap becomes 886.
7. Adapting to a project
Standard dimensions fit standard appliances. A project with a professional range, an integrated fridge or an accessible counter will depart from them. Decide which dimensions are fixed (appliance, ceiling, door swing) and which are flexible (cabinet width, filler) before drawing. The sizes by type guide covers the widths in more detail.
8. Checking a drawing
Check five things on any cabinet drawing: the reference point, the counter thickness, the appliance dimensions, the filler allowance and the ceiling height. If all five are on the drawing, most dimension errors are already eliminated. If one is missing, ask before production, not after.
9. قائمة مراجعة قبل الالتزام
قبل التوقيع، تأكد من ستة أمور: جودة اللوحة، طراز الجهاز، نظام التشطيب، معيار التعبئة، نطاق الفحص، وجدول الدفع. يجب توثيق كل منها كتابيًا، وليس عبر مكالمة هاتفية. تُحوّل قائمة التحقق من عرض الأسعار هذه الأمور الستة إلى مقارنة موجزة في صفحة واحدة.
10. الأخطاء الشائعة
الخطأ الأكثر شيوعًا هو مقارنة سعر المصنع بالتكلفة النهائية بعد الشحن. ثانيًا، إغفال تكلفة الفحص في الميزانية. ثالثًا، دفع المبلغ المتبقي قبل الموافقة على الفحص. يمكن تجنب كل هذه الأخطاء بتحديد نطاق العمل كتابيًا وإجراء فحص ما قبل الشحن.
11. كيفية قياس الغرفة
قِس كل جدار عند ثلاث نقاط: الأعلى، والوسط، والأسفل، واستخدم أصغر قياس. نادرًا ما تكون الجدران مربعة تمامًا، وانحناء بمقدار ١٠ ملم على امتداد ثلاثة أمتار يُغيّر نوع الحشو. قِس السقف عند كل زاوية، وسجّل مواقع المقابس الكهربائية، والمشعات، وأنابيب الصرف الصحي قبل الرسم. يوفر المسح الدقيق وقتًا أطول من الرسم السريع، ويحتوي دليل القياس على ورقة قابلة للطباعة.
الأسئلة المتكررة
What is the standard base cabinet depth?
600 mm (24 in) including the door. The carcass is usually 560–580 mm to allow for the door and a service gap at the wall.
What is the standard counter height?
900 mm (36 in) in most markets, with a range of 850–920 mm depending on the user and the appliance. The carcass is typically 720 mm plus counter thickness.
How high should wall cabinets be?
600–900 mm high, with the bottom 450–600 mm above the counter. The exact height depends on ceiling height and whether a bulkhead is used.
What is the gap between counter and wall cabinet?
450–600 mm is common. Less than 450 mm crowds the worktop; more than 600 mm wastes storage and makes the top shelf hard to reach.
How wide can a cabinet be?
600–900 mm for base cabinets, 600–1,000 mm for wall cabinets. Above 900 mm, a single door becomes heavy and a double door is better.
Do dimensions change between countries?
Yes. The US uses inches and a 36 in counter; metric markets use 900 mm. The difference is small but matters for appliance and counter cut-outs.
