How Much RAM Do You Really Need? (By Use Case)

Disclosure: We may earn a commission from qualifying purchases through links on this page, at no extra cost to you. Learn more.

For most people in 2026, 16 GB is the sweet spot. 8 GB still works for light use, but 16 GB gives comfortable headroom, and 32 GB+ is for heavy creative or professional workloads. Here’s how to choose.

RAM by what you do

Use case Recommended RAM
Basic (web, email, streaming, documents) 8 GB
Everyday multitasking / mainstream use 16 GB
Gaming 16 GB (32 GB for high-end)
Photo editing, light video, many browser tabs 16–32 GB
4K video editing, 3D, virtual machines 32–64 GB

Signs you don’t have enough

  • Slowdowns when switching between apps or with many tabs open.
  • Heavy disk activity as the system swaps memory to storage.
  • Programs crashing or “low memory” warnings.

RAM isn’t the only thing

If your machine feels slow, an SSD upgrade often matters more than extra RAM. And on many laptops, RAM is soldered — so buy enough up front. Pair the right RAM with adequate storage; our Storage Calculator helps size that.

Do You Need a Hub for Smart Lights?

Disclosure: We may earn a commission from qualifying purchases through links on this page, at no extra cost to you. Learn more.

It depends on the technology. Wi-Fi and Bluetooth smart bulbs work without a hub. Bulbs that use Zigbee, Z-Wave, or Thread generally need a hub (or a compatible smart speaker/router that has one built in).

No hub needed

  • Wi-Fi bulbs — connect straight to your router and app. Easiest to start with; fine for a few bulbs. Downside: lots of bulbs can clutter your Wi-Fi.
  • Bluetooth bulbs — pair directly to your phone, but only work in range and usually for one user.

Hub recommended or required

  • Zigbee / Z-Wave (e.g. Philips Hue) — need a hub, but it’s more reliable at scale, faster, and doesn’t burden your Wi-Fi.
  • Thread / Matter — need a Thread border router, which is increasingly built into smart speakers, hubs, and some routers.

Which should you choose?

Your situation Best pick
Just a few bulbs, keep it simple Wi-Fi bulbs (no hub)
Whole-home, reliability matters Zigbee/Thread + hub
Already own a recent smart speaker Check if it’s a built-in hub

Do You Need a Soundbar With a 4K TV?

Disclosure: We may earn a commission from qualifying purchases through links on this page, at no extra cost to you. Learn more.

You don’t strictly need one — but most people should get one. A 4K TV upgrades the picture, not the sound. Modern TVs are thin, which leaves no room for good speakers, so audio is often the weakest part of an otherwise great TV.

Why TV speakers disappoint

Slim panels force tiny, downward- or rear-firing speakers. The result is thin sound, weak bass, and dialogue that’s hard to follow during action scenes. A soundbar fixes all three for a modest price.

When a soundbar is worth it

  • You watch movies, sports, or games and want impact and clear dialogue.
  • You find yourself turning on subtitles to follow speech.
  • Your TV is 55 inches or larger — the bigger the screen, the more the weak audio stands out.

When you can skip it

  • You mostly watch casual daytime TV at low volume.
  • You already have an AV receiver and speakers.

What to look for

Even an entry-level 2.1 soundbar (bar + subwoofer) is a big upgrade. For movies, look for Dolby Atmos support and HDMI eARC for the best connection to your TV.

Can You Fly a Drone in the Rain, Wind, or Cold?

Most consumer drones are not waterproof and aren’t designed for rain. Here’s what weather they can and can’t handle — and how to fly safely when conditions aren’t perfect.

Rain

Avoid it. Nearly all popular camera drones (including DJI’s consumer models) lack a waterproof rating, and moisture can damage motors and electronics. Light mist for a moment may be survivable, but steady rain risks your drone. A handful of specialised enterprise/agriculture drones are weather-sealed — check the spec sheet.

Wind

Small drones can fly in light-to-moderate wind, but there’s a limit. A rough guide: keep total wind (including gusts) below about two-thirds of the drone’s top speed. Sub-250 g drones are especially affected by gusts. If it’s struggling to hold position, land.

Cold

Lithium batteries lose capacity and voltage in the cold, cutting flight time and risking sudden power drops. In cold weather: keep batteries warm until takeoff, hover for a minute to warm the pack, and land with more reserve than usual.

Fog, snow, and heat

  • Fog/snow — moisture risk plus poor visibility; generally avoid.
  • Heat — watch for overheating on long summer flights; give the drone rest.

Do Smart Plugs Use Electricity When Off?

Disclosure: We may earn a commission from qualifying purchases through links on this page, at no extra cost to you. Learn more.

Yes — but barely. A smart plug draws a tiny amount of standby power (typically around 1 watt or less) even when the connected device is switched off, because it stays connected to Wi-Fi to receive commands. Over a year that’s usually well under a dollar or two in electricity.

Why it uses any power at all

A smart plug is always listening for your app, voice assistant, or schedule. Keeping the Wi-Fi radio and controller alive uses a small trickle of standby (vampire) power. That’s the trade-off for remote control and automation.

Do smart plugs actually save money?

They can — if you use them to cut off other devices’ standby draw. TVs, game consoles, chargers, and coffee makers can each waste several watts doing nothing. Automating them off overnight typically saves far more than the plug itself consumes.

Getting the most from them

  • Put them on the biggest standby wasters (entertainment centres, old electronics).
  • Use schedules and “away” routines to cut power automatically.
  • Check plug ratings — don’t exceed the amperage for high-draw appliances like space heaters.

Do You Need a License to Fly a Drone? (2026 US Guide)

It depends on why you’re flying. In the United States, recreational and commercial drone flying have different rules. Here’s the plain-English version — but always confirm current requirements with the FAA, because drone regulations change.

Flying for fun (recreational)

  • You must pass the free TRUST test (The Recreational UAS Safety Test) and carry proof.
  • Drones over 250 g (0.55 lb) must be registered with the FAA (a small fee), and many now require Remote ID.
  • Drones under 250 g — such as the popular DJI Mini series — generally don’t need registration for purely recreational flying, but you still take the TRUST test and follow the rules.

Flying for work (commercial)

If you’re paid or flying for a business (real estate photos, inspections, content), you need the FAA Part 107 Remote Pilot Certificate, regardless of drone weight. That involves passing a knowledge exam.

The core rules everyone follows

  • Keep the drone within visual line of sight.
  • Stay below 400 ft and away from airports and restricted airspace.
  • Don’t fly over people or moving vehicles unless permitted.
  • Check airspace with an app like B4UFLY before you fly.

Disclosure: some links below are affiliate links. We may earn a commission from qualifying purchases at no extra cost to you. This never affects our recommendations.

Short answer: a 128 GB card holds roughly 25,000 JPEG photos from a typical smartphone or mid-range camera (around 5 MB each). Shoot in RAW and that drops to about 4,000–5,000. Use the calculator below for your exact file sizes.

Photos per 128 GB by file size

Average photo size Approx. photos on 128 GB
3 MB (phone JPEG, compressed) ~42,000
5 MB (typical JPEG) ~25,000
15 MB (high-res JPEG) ~8,500
25 MB (RAW) ~5,000

Usable space is a little lower than the label (formatting overhead), so treat these as close estimates.

Don’t forget video

If you also shoot 4K video, storage disappears fast — about 30 GB per hour. See how much storage you need for 4K video.

Rule of thumb: consumer 4K video eats roughly 30 GB per hour at common bitrates — so an hour of 4K needs about six times the space of the same hour at 1080p. Use the calculator below to size your storage for photos and video together.

Storage per hour by resolution

Resolution Approx. storage per hour
1080p ~8 GB
4K ~30 GB
8K ~120 GB

High-frame-rate, high-bitrate, or professional (log/RAW) footage can be several times larger, so treat these as consumer baselines.

What capacity should you buy?

You shoot… Practical capacity
Occasional 4K clips 256–512 GB
Regular 4K vlogging 1–2 TB
Heavy 4K/8K or archives 4 TB+ (SSD or NAS)

Where to store it

  • microSD / SD — in-camera capture. See how many photos 128GB holds.
  • Portable SSD — fast offload and editing on the go.
  • External HDD / NAS — cheap bulk archiving.

Short answer: for a 65-inch 4K TV, a comfortable, immersive seating distance is roughly 5.4 to 8.7 feet (about 1.6–2.7 m). Sit closer for a more cinematic feel, farther for a relaxed view. Use the calculator below for other sizes and resolutions.

Why resolution changes the answer

A 4K panel has four times the pixels of 1080p, so you can sit closer without seeing individual pixels. That’s why 4K TVs can be viewed nearer than older HD sets of the same size — and why 8K lets you sit closer still.

65-inch distance by resolution

Resolution Comfortable range
1080p ~8.7–13.5 ft
4K ~5.4–8.7 ft
8K ~3.8–6.5 ft

Don’t forget mounting height

Aim for the middle of the screen to sit around eye level when seated — usually a bit lower than people expect. Too high causes neck strain.

If your sofa sits about 12 feet from the wall, a 75-inch to 85-inch 4K TV hits the sweet spot for an immersive picture without overwhelming the room. Here’s how to dial it in.

The quick guideline

For 4K, a common rule is that a comfortable diagonal is roughly the viewing distance (in inches) times 0.6 to 0.84. At 12 feet (144 inches) that’s about 86 to 121 inches of diagonal for full immersion, so 75–85 inches is a very comfortable, practical range for most people.

TV size by viewing distance (4K)

Distance Comfortable 4K size
8 ft 55–65 in
10 ft 65–75 in
12 ft 75–85 in
14 ft+ 85 in and up

Bigger is usually better — within reason

Most people underestimate the size they want and rarely regret going larger with 4K. The limit is when you can’t comfortably see the whole screen from your seat. Get an exact range with our TV Viewing Distance Calculator.
