Tablespoon vs Teaspoon: What's the Difference?
If you've ever mixed up a tablespoon and a teaspoon in a recipe, you know how much it matters. Accidentally using a tablespoon of salt when the recipe calls for a teaspoon results in food three times saltier than intended. Here's everything you need to know.
The Key Facts
1 tablespoon (tbsp) = 3 teaspoons (tsp). A tablespoon is three times larger than a teaspoon. In milliliters: 1 tablespoon = 14.8ml, 1 teaspoon = 4.9ml. This ratio holds in both US customary and metric-adjacent cooking measurements.
How to Tell Them Apart
In recipes, tablespoon is abbreviated as "tbsp", "tbs", "T", or "Tbsp" — "tbs" and "tbsp" are used interchangeably and mean exactly the same thing. Teaspoon is abbreviated as "tsp" or "t". The capital T is tablespoon, the lowercase t is teaspoon — a helpful trick for reading handwritten recipes.
On measuring spoons, tablespoon is always the largest spoon in the set. Teaspoon is the second largest (after tablespoon), followed by ½ tsp and ¼ tsp. Most measuring spoon sets include: 1 tbsp, 1 tsp, ½ tsp, and ¼ tsp.

Common Mistakes to Avoid
The most common mistake is using the wrong spoon when a set has been separated. Before cooking, always identify which spoon is which — most sets have the measurement printed on the handle. If yours has worn off, a standard tablespoon is roughly the size of a large soup spoon, while a teaspoon is roughly the size of a small coffee spoon.
Another common error: confusing "1 tablespoon" with "1 soup spoon from the drawer." Regular cutlery spoons are not standardized to cooking measurements. A soup spoon from your silverware drawer might hold anywhere from 8ml to 18ml — not reliably 14.8ml like a measuring tablespoon.
When Precision Really Matters
For salt, baking soda, baking powder, and strong spices — precision matters a lot. Being off by even a teaspoon can ruin a dish. Baking soda is particularly sensitive: too much and baked goods taste metallic; too little and they don't rise properly.
For herbs, olive oil, and other forgiving ingredients, a rough estimate is usually fine. A little more basil in a tomato sauce won't change the dish the way an extra teaspoon of baking soda changes a cake.
Converting Teaspoons to Tablespoons (and Back)
To convert teaspoons to tablespoons: divide by 3. So 6 teaspoons = 2 tablespoons. To convert tablespoons to teaspoons: multiply by 3. So 2.5 tablespoons = 7.5 teaspoons. Use our converter tool whenever you need to convert between units quickly without doing the math.
Frequently Asked Questions
How many teaspoons are in a tablespoon?
There are exactly 3 teaspoons in 1 tablespoon. This is the same in US measurements, and it's a ratio worth memorizing — it comes up constantly in cooking and baking. If a recipe calls for 1 tablespoon and you only have a teaspoon measure, use it 3 times.
Is a dessert spoon the same as a tablespoon?
No. A dessert spoon is a British measurement equal to 2 teaspoons (about 10ml), which sits between a teaspoon and a tablespoon. It's rarely used in American recipes but appears in older British cookbooks. A tablespoon is 14.8ml; a dessert spoon is 10ml.
How many tablespoons are in ¼ cup?
There are 4 tablespoons in ¼ cup. A full cup contains 16 tablespoons, so ¼ cup is 4 tablespoons, ½ cup is 8 tablespoons, and ¾ cup is 12 tablespoons. This is useful to know when scaling recipes or when you need a cup measurement but only have tablespoon spoons available.
What if a recipe says "1 tbsp" — does that mean level or heaping?
In standard recipe writing, measurements are assumed to be level unless specified otherwise. A level tablespoon means you fill the spoon and scrape the top flat with a straight edge. "Heaping" means the ingredient mounds above the spoon. When precision matters (baking, spices), always measure level.
International Tablespoon Sizes
Not every country's tablespoon matches the US 14.79ml standard. Australia uses a notably larger 20ml tablespoon — four teaspoons instead of three — which can throw off a recipe if you don't know to adjust. The UK and Canada use a tablespoon close to 15ml, essentially matching the US size for practical purposes. When following a recipe from Australia specifically, either use an Australian tablespoon measure or convert: multiply the Australian tablespoon count by roughly 1.33 to get the equivalent number of US tablespoons.
Why does this size difference matter more for baking than cooking?
Baking relies on precise ratios between leavening agents, liquid, and dry ingredients to work correctly, so using an Australian tablespoon (33% larger) where a US tablespoon was intended can meaningfully throw off a cake or bread recipe's structure. General cooking — sauces, seasoning, marinades — is far more forgiving, since a slightly larger or smaller spoonful of oil or spice rarely ruins the dish.
