When it comes to baking sourdough, precision isn’t just a nice-to-have—it’s essential. Unlike traditional baking where volume measurements (like cups and spoons) might suffice, sourdough relies on exact ratios of flour to water, known as hydration levels. Even a slight deviation can dramatically affect your starter’s activity, fermentation time, and final loaf texture. That’s why investing in a reliable kitchen scale isn’t optional for serious sourdough bakers—it’s foundational. Whether you’re feeding your starter daily or scaling up for a weekend bake, the right scale ensures consistency, repeatability, and confidence in your results.
This comprehensive buying guide is designed to help you navigate the crowded market of kitchen scales with clarity and confidence. We’ll walk you through every critical factor—from accuracy and capacity to build quality and smart features—so you can choose a scale that fits your baking style, kitchen setup, and budget. You’ll learn how to avoid common pitfalls, understand what different price tiers deliver, and discover expert tips for getting the best value. By the end, you’ll have all the knowledge needed to pick a scale that becomes your most trusted tool in the sourdough journey.
The kitchen scale market has evolved significantly over the past decade. Once limited to basic mechanical models, today’s digital scales offer features once reserved for professional labs: high-precision sensors, tare functions, multiple units, and even Bluetooth connectivity. For sourdough enthusiasts, this means more control than ever before. However, with so many options—ranging from under $20 to over $100—it’s easy to feel overwhelmed. This guide cuts through the noise, focusing specifically on what matters most for sourdough: accuracy at small weights, durability for daily use, and intuitive operation during early-morning feedings or late-night bakes.
What to Look for When Buying a Kitchen Scale
1. Accuracy and Precision
When feeding a sourdough starter, you’re often working with just 20–50 grams of flour or water. At these tiny weights, even a 1-gram error can throw off your hydration percentage by several points—enough to stall fermentation or create a dense crumb. That’s why accuracy is non-negotiable. Look for scales that measure in 0.1-gram increments (also called resolution). While some budget models claim “high precision,” they may only be accurate to ±1 gram, which isn’t sufficient for sourdough.
True precision means the scale consistently returns the same reading for the same weight across multiple tests. A good way to test this at home is by using calibrated weights (like coins or known-weight objects). For example, a U.S. nickel weighs exactly 5 grams—place one on the scale, remove it, and repeat five times. If the readings vary, the scale lacks repeatability. Top-tier scales like the OXO Good Grips or My Weigh iBalance maintain ±0.1g accuracy even after repeated use.
2. Capacity and Range
Sourdough bakers need a scale that handles both micro-measurements (for starter feeds) and larger batches (for full loaves). Most sourdough recipes call for 500g–1000g of total flour, so a minimum capacity of 5kg (11 lbs) is ideal. However, don’t assume higher capacity means better performance—some scales lose accuracy at lower weights when designed for heavy-duty use.
Look for a scale with a broad range: capable of measuring down to 0.1g while handling up to 5kg. This dual capability ensures you can weigh a tiny pinch of yeast or a full batch of dough without switching tools. Scales like the Escali Primo or AWS Series offer this balance well. Avoid models with a 10kg+ capacity unless you regularly bake in bulk—they often sacrifice low-end sensitivity.
Also consider the platform size. A compact platform (around 5–6 inches) is perfect for small bowls and jars used in starter maintenance, while larger platforms accommodate mixing bowls for dough. Some scales come with removable platforms for easy cleaning—a major plus when dealing with sticky dough residue.
3. Build Quality and Durability
Your kitchen scale will likely see daily use: morning feedings, evening bakes, occasional spills, and flour dust. Cheap plastic housings crack, buttons wear out, and sensors drift over time. Invest in a scale built to last. Stainless steel platforms resist corrosion and are easy to wipe clean. Reinforced ABS plastic or metal casings handle drops better than flimsy alternatives.
Check the button quality too. Tactile, responsive buttons (like those on the OXO or Tanita models) make taring quick and reliable. Membrane buttons on budget scales often stick or fail after months of use. Also, consider water resistance—while no kitchen scale is fully waterproof, some (like the My Weigh KD8000) have sealed sensors that survive minor splashes.
Longevity matters because replacing a broken scale mid-bake is frustrating and costly. A $40 scale that lasts three years is a better value than a $20 model that fails in six months. Read user reviews for mentions of “sensor drift,” “cracked platform,” or “unresponsive buttons”—these are red flags.
4. Features & Functionality
Beyond basic weighing, modern scales offer features that streamline sourdough baking:
– Tare Function: This lets you zero out the weight of a bowl or container so you only measure the ingredient inside. Essential for adding flour and water separately without math.
– Unit Conversion: Switch between grams, ounces, pounds, milliliters (for water), and even baker’s percentages. Look for one-touch switching—not buried menus.
– Auto-Off: Saves battery life but can be annoying if it shuts off mid-recipe. Some scales let you disable this feature.
– Backlit Display: Crucial for early-morning or dimly lit kitchens. A bright, clear LCD helps you read measurements quickly.
– Timer Function: Handy for tracking fermentation times or proofing stages without pulling out your phone.
– Bluetooth/App Connectivity: Advanced models (like the Greater Goods Nourish) sync with apps to log feeds, track starter activity, or convert recipes. Useful for data-driven bakers but not essential.
For sourdough, prioritize tare, unit flexibility, and a backlit display. Avoid scales with overly complex menus—you want speed and simplicity during busy baking sessions.
5. Brand Reputation and Reliability
Not all scales are created equal, even if they look similar. Established brands like OXO, Escali, My Weigh, Tanita, and AWS have decades of experience in precision weighing. They invest in quality control, customer support, and consistent calibration. Generic or no-name brands often cut corners on components, leading to inconsistent performance.
Check brand warranties and customer service responsiveness. OXO offers a 10-year warranty on many models—rare in this category. Escali provides lifetime support and free calibration guides. My Weigh specializes in high-precision scales for bakers and includes detailed user manuals.
User communities also matter. Brands with active forums or Reddit threads (like r/Breadit or The Fresh Loaf) often have loyal followings who share troubleshooting tips and long-term reviews. A scale praised by experienced bakers is more trustworthy than one with only Amazon reviews.
6. Warranty and Customer Support
A good warranty signals confidence in product quality. Most reputable scales come with at least a 1–2 year warranty, covering defects and sensor issues. Some, like OXO, extend this to 10 years. Avoid brands with no warranty or vague terms.
Customer support is equally important. If your scale starts drifting or the display fails, can you get a replacement quickly? Look for companies with U.S.-based support, clear contact info, and responsive email or chat. Amazon reviews often mention support experiences—pay attention to replies from the seller or brand.
Also check return policies. Many retailers (like Amazon, Williams Sonoma, or Sur La Table) offer 30-day returns, giving you time to test accuracy and usability. Some brands even provide free return shipping for defective units.
7. Size and Portability
Kitchen space is precious, especially for home bakers. A compact scale (under 8 inches wide) fits easily on countertops or in drawers. However, don’t sacrifice functionality for size—some ultra-compact models have tiny platforms that don’t fit standard bowls.
Weight matters too. A lightweight scale (under 2 lbs) is easy to move, but heavier models often feel more stable and durable. If you bake frequently, stability prevents accidental bumps during weighing.
Consider foldable or detachable designs. The My Weigh iBalance has a slim profile and folds flat for storage. Others include protective covers that double as trays. For travel or small apartments, portability is a real advantage.
8. User Reviews and Real-World Testing
Spec sheets tell part of the story—real user experiences complete it. Look beyond star ratings and read detailed reviews. Ask: Does the scale handle small weights accurately? Does the tare function work smoothly? Does it survive flour spills?
Pay attention to long-term reviews (6+ months). Sensor drift is a common issue—scales that were accurate initially may lose calibration over time. Users often note this in updates. Also check for consistency across platforms: Amazon, Best Buy, and specialty baking sites may have different feedback.
Join sourdough forums or Facebook groups and ask for recommendations. Experienced bakers share honest insights about which scales they’ve kept for years—and which they’ve replaced.
Different Types of Kitchen Scales
Common Buying Mistakes to Avoid
❌ Mistake: Prioritizing Price Over Precision
Why it’s bad: A $15 scale might seem like a bargain, but if it can’t measure below 1g accurately, your sourdough starter will suffer. Inconsistent feeds lead to unpredictable fermentation, wasted ingredients, and frustration.
What to do instead: Invest in a scale with 0.1g resolution, even if it costs $40–$60. Think of it as a long-term tool—not a disposable gadget.
❌ Mistake: Ignoring Platform Size
Why it’s bad: A tiny platform forces you to use small containers, making it hard to mix ingredients or tare large bowls. You’ll constantly reposition items, increasing error risk.
What to do instead: Choose a scale with a platform at least 5 inches in diameter. Removable platforms are a bonus for cleaning.
❌ Mistake: Overlooking Tare Function Quality
Why it’s bad: A slow or unresponsive tare button disrupts your workflow. You might skip taring altogether, leading to incorrect measurements.
What to do instead: Test the tare function in-store or read reviews. Look for instant zeroing with a single press.
❌ Mistake: Buying Based on Looks Alone
Why it’s bad: Sleek designs don’t guarantee performance. Some stylish scales use fragile materials or have poor sensor placement.
What to do instead: Focus on functionality first. A plain but reliable scale beats a beautiful paperweight.
❌ Mistake: Skipping Unit Flexibility
Why it’s bad: Recipes vary by region—some use grams, others ounces or milliliters. A scale locked to one unit forces conversions, increasing error chances.
What to do instead: Ensure the scale supports grams, ounces, pounds, and fluid ounces (for water). One-touch switching is ideal.
❌ Mistake: Ignoring Battery Life and Type
Why it’s bad: Scales that drain AA batteries quickly become inconvenient. Some use proprietary batteries that are hard to replace.
What to do instead: Choose models with long battery life (6+ months) or USB rechargeability. Avoid scales requiring rare battery types.
❌ Mistake: Not Testing Before Committing
Why it’s bad: You might discover flaws only after purchase—like a dim display or sticky buttons—when it’s too late to return.
What to do instead: Buy from retailers with generous return policies. Test accuracy, tare, and display clarity within the first week.
Budget Guidelines: How Much Should You Spend?
– Entry-Level ($20–$35): These scales offer basic functionality but often lack precision below 1g. Platforms may be small, and build quality is typically plastic-heavy. Suitable for occasional bakers who don’t mind slight inconsistencies. Examples: Amazon Basics, OXO Good Grips (basic model). Expect to replace within 1–2 years.
– Mid-Range ($35–$70): The sweet spot for most sourdough enthusiasts. These scales deliver 0.1g accuracy, durable construction, and reliable tare functions. Brands like Escali, My Weigh, and AWS dominate this tier. You’ll get 3–5 years of consistent performance with proper care.
– Premium ($70–$120): Designed for serious bakers and small-scale professionals. Features include stainless steel platforms, advanced sensors, app connectivity, and extended warranties. Models like the Greater Goods Nourish or Tanita KD-165 offer lab-grade precision and smart features. Ideal if you bake weekly or track detailed metrics.
– Luxury ($120+): Commercial-grade scales used in bakeries and test kitchens. Built for heavy daily use, with reinforced frames, IP-rated water resistance, and calibration certificates. Overkill for most home bakers, but worth considering if you run a cottage bakery or demand absolute consistency.
Expert Tips for Getting the Best Deal
– Buy During Sales Events: Kitchen scales often go on sale during Black Friday, Prime Day, and post-holiday clearances. Sign up for brand newsletters (OXO, Escali) to get early access to discounts.

– Consider Refurbished Models: Brands like OXO and My Weigh sell certified refurbished scales at 20–30% off. These come with full warranties and are thoroughly tested.
– Read the Fine Print on Warranties: Some warranties require registration within 30 days. Keep your receipt and register immediately after purchase.
– Test Accuracy at Home: Use household items with known weights (e.g., 5g nickel, 28g AA battery) to verify your scale’s precision. Recalibrate annually if the model allows.
– Prioritize Return Windows: Choose retailers with 30–60 day return policies. This gives you time to test under real baking conditions.
– Avoid “Too Good to Be True” Deals: Scales under $15 with 0.1g accuracy are usually misleading. Check reviews for “fake precision” complaints.
– Bundle with Other Tools: Some retailers offer discounts when you buy a scale with a dough scraper, banneton, or flour sifter. Great for new bakers building their kit.
Frequently Asked Questions
Q: Do I really need a scale for sourdough starter?
A: Yes. Sourdough relies on precise hydration ratios (typically 1:1:1 for starter feeds). Volume measurements (cups) are inconsistent due to flour compaction. A scale ensures every feed is identical, leading to predictable fermentation and stronger starters.
Q: Can I use my bathroom scale for baking?
A: No. Bathroom scales measure in 100g+ increments and aren’t designed for kitchen use. They lack tare functions and can’t handle small weights accurately.
Q: How often should I calibrate my kitchen scale?
A: Most digital scales don’t require frequent calibration, but it’s wise to test accuracy every 6–12 months using known weights. Some models (like My Weigh) have built-in calibration modes.
Q: What’s the difference between grams and milliliters on a scale?
A: Scales measure weight, not volume. However, for water (density = 1g/ml), 1ml ≈ 1g. This conversion is built into many scales for convenience, but it doesn’t apply to flour, oil, or honey.
Q: Can I weigh sourdough starter directly in its jar?
A: Yes—use the tare function. Place the jar on the scale, press tare, then add your discard or fresh flour/water. This keeps your starter container clean and accurate.
Q: Are smart scales worth it for sourdough?
A: Only if you enjoy data tracking. Apps can log feeds, remind you of feeding times, and analyze activity patterns. But for most bakers, a reliable non-smart scale is simpler and more durable.
Q: What if my scale stops being accurate?
A: First, replace the batteries. If that doesn’t help, check for debris under the platform. If the issue persists, contact the manufacturer—many offer free recalibration or replacement under warranty.
Q: Can I use a scale for other kitchen tasks?
A: Absolutely. A good kitchen scale works for coffee brewing, spice blending, portion control, and even postage. It’s a versatile tool beyond baking.
Q: How do I clean my kitchen scale?
A: Wipe the platform with a damp cloth and mild soap. Avoid submerging the unit. For sticky dough, use a soft brush. Never spray water directly on the display or buttons.
Q: Should I buy a scale with a timer?
A: It’s helpful but not essential. If you already use a phone or oven timer, you may not need this feature. However, having a built-in timer reduces clutter and keeps your hands free.
