For what do you want to use your new food scale?
If you are looking for an easy to use weighing assistant for your daily work in the kitchen, you should choose one with a simple two-button operation. One button for on- and off and the tare function. The other button to choose the measure in grams or ounces (kg / lb). With the tare function, you can always set the weight to zero and weigh only the new ingredient for your food or cake preparation.
Is it necessary to weight heavy items? For a normal use in the kitchen, a maximum weight of 11 lb or 5 kg should be sufficient. Most available kitchen scales inclusive the smaller and cheaper units can weigh items up to this range.
In addition, the size of the food is of some importance. The food scale has to have a respective size so that you can place also bigger parts without any problems. This mainly comes along with heavier weights so that you have to consider this with your scale selection.
Another often-asked feature is the use for a diet program. For this application are special nutrition scales the best choice. There is a variety of nutrition scales from different brands available. A good recommendation is the EatSmart Digital Nutrition Scale – Professional Food and Nutrient Calculator or the Escali Cibo Nutritional Scale.
How much money do you want to spend?
You can purchase a small and easy to use food scale in a reasonable or good quality in the range of 20-30$. Here is the EatSmart Precision Pro Digital Kitchen Scale a good choice. This small scale got many good reviews.
A food scale with more functions, in a bigger size, or for weighing higher weights is more expensive. Nevertheless, you can get many good scales in the range of 50-100$. Respective nutrition scales are also available in this price range. Finally, the upper limit depends only on your requirements and your wallet.
Compact size or stand-alone unit?
This is a question of your available space in the kitchen and your personal preferences. A small food scale is easy to store and you can take it every time only when you need it.
The other alternative is a stand-alone scale in a bigger size. If you use your scale very often, it is more convenient to have it all the time available. It can also be a question of design. A nice and technically designed food scale can be an eye catcher in your kitchen interior.
Where to buy a food scale?
This is always a matter of trust. The online world with thousands of shops does not make this easier. In general I would like to recommend big and well known online shops with respective shopping terms, return policies, secure payment systems, a huge choice of the searched products, excellent customer service and last but not least good prices. My personal odds-on favorite is Amazon.
If you follow your answer to your question what kind of food scale you really need and how much you would like to spend, it should be easy to find the best scale for your kitchen.
