Which refrigerator size do you need?
The Space You Have
First you need to consider the available space for your new fridge – the length, depth and height. In most cases, this step can give you a rough idea of future fridge size. If needed, you need to also measure the kitchen’s space to evaluate how much proportion the refrigerator may take.
The Capacity You Need
The other concern is you need to consider how much food you usually store in a fridge. The proportion of freezer food and refrigerator food also needs to be considered. How many family members you have can affect the needed capacity.
Common Fridge Sizes
Most fridges fall into three capacity bands. Pick based on household size, cooking habits and kitchen space.
Small-capacity
Good for singles, couples who eat out frequently, rental units or pantries/dry kitchens.
Why it’s great: Compact, easier to place, budget-friendly.
Typical formats: Top-mount, single-door with small freezer, or slim bottom-mount.
Fit notes: Look for adjustable shelves and reversible doors to maximise tight spaces.
Medium-capacity
The most popular size in Singapore, ideal for couples to small families (2–4 people).
Why it’s great: Balanced footprint vs storage; fits most standard cavities.
Typical formats: Bottom-mount (fresh food at eye level) or Top-mount (value-friendly).
Fit notes: Often available in counter-depth options to keep walkways clear.
Large-capacity
Best for bigger families (3–6 people), weekly bulk shops, or anyone who meal-preps and hosts often.
Why it’s great: Wide shelves; larger crispers; more freezer space for batch-cooked meals.
Typical formats: French Door / 4-Door, Side-by-Side.
Fit notes: Check the fridge dimensions; measure corridors/lifts for delivery access.
How can you measure for a new refrigerator?
Before buying a new fridge, it’s important to measure carefully to ensure a perfect fit. Start by measuring the width, height and depth of the space where you plan to place the refrigerator. Leave at least 2–5 cm of clearance on each side and at the back to allow proper air circulation and easy door movement.
Don’t forget to check the door opening space — make sure there’s enough room for the doors to swing open fully without hitting walls or cabinets.
If needed, also measure the pathway to your kitchen, including doorways, corridors and lifts, to confirm the appliance can be delivered without issues. Taking a few extra minutes to measure accurately will save you from the hassle of tight fits or delivery problems later on.
FAQs
Q1: How much ventilation or clearance do I need around a refrigerator?
Typically you’ll want 1–2 inches (2.5–5 cm) at the back, some clearance above, and minimal side space (e.g. ⅛–½ inch) for airflow. Also leave room for the doors to open freely.
Q2: Does a larger refrigerator use significantly more energy?
Yes — bigger size generally means more energy use, especially if it’s not well insulated or ventilated. Choosing a size that fits your actual needs helps avoid wasted capacity and extra power draw.
Q3: If my family grows or my cooking habits change, can I “oversize” the refrigerator now?
You can, but oversizing too much may lead to underuse of capacity (wasting energy). A balanced margin is okay, but going too big might not be wise unless you know your habits will change dramatically.
Q4: What should I do if my alcove or nook is not a perfect rectangle?
Measure at multiple points (top, middle, bottom) and take the narrowest dimensions. Always allow buffer space rather than pushing a tight fit.
