Canva Smart Mockups: What They Are & How to Use Them

Canva Smart Mockups are a feature that automatically places your design onto a realistic photo of an object—like a t-shirt, phone screen, or coffee mug—so you can present your work in context without using Photoshop or hiring a photographer. To use one, you open a Smart Mockup template in Canva, drag your design onto the highlighted area, and the image updates instantly. The feature is built into Canva Pro, Canva for Education, and Canva for Nonprofits, and it works entirely in your browser.

Formula

The calculator works out your average pace and speed for a run, walk, or cycle. The formulas are:

• Average pace = finish time ÷ distance (in minutes per kilometer)
• Average speed = distance ÷ (finish time ÷ 60) (in kilometers per hour)

Where:

• t = total finish time in minutes (e.g., 50 minutes)
• d = distance in kilometers (e.g., 10 km)

All values are positive numbers. The pace is shown as a decimal (e.g., 5.00 min/km), and speed is shown to two decimal places.

Worked Example

Using the default values from the calculator—finish time = 50 minutes, distance = 10 km—the steps are:

1. Calculate pace: 50 ÷ 10 = 5.00 minutes per kilometer.
2. Calculate speed: 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h.

So the average pace is 5.00 min/km and the average speed is 12.00 km/h. This matches the calculator’s output for the defaults.

When to Use This Calculator

Use this calculator any time you want to know your running or cycling pace for a training plan, race, or casual fitness tracking. It is especially useful when you have a finish time and distance but want to compare efforts across different routes or workouts. For example, if you run 5 km in 30 minutes, your pace is 6.00 min/km and your speed is 10 km/h. If you cycle 20 km in 60 minutes, your pace is 3.00 min/km and your speed is 20 km/h.

How to Read the Result

The first output (pace) is the headline answer. A lower pace number means faster—5.00 min/km is faster than 6.00 min/km. The speed output is the same information expressed differently: higher speed means faster. Both are useful depending on your context. Runners often think in pace (min/km or min/mile), while cyclists and drivers think in speed (km/h or mph). The calculator gives you both so you don’t have to convert manually.

Common Mistakes and Unit Mix-Ups

• Using miles instead of kilometers: If you run a 10-mile race, the distance must be entered as 16.09 km (since 1 mile = 1.609 km). The calculator assumes kilometers only.
• Entering time in hours instead of minutes: If your finish time is 1 hour 30 minutes, enter 90, not 1.5. The calculator expects minutes.
• Confusing pace and speed: Pace is time per unit distance (min/km); speed is distance per unit time (km/h). They are reciprocals, so a mistake here leads to a very wrong answer.
• Rounding too early: If you round the pace to 5.0 and then compute speed, you might get 12.0 instead of 12.00. The calculator rounds only at the end, so keep full precision during calculations.

Limits of This Formula

This calculator gives an average pace and speed over the whole distance. It does not account for:

• Elevation changes: A hilly route will have a slower pace than a flat one, even if the average is the same.
• Stops and pauses: If you stop for water or traffic lights, your moving time is less than your total time, so your actual moving pace will be faster.
• Units: The calculator only works in kilometers and minutes. If you need miles or hours, you must convert first.

For race planning, use this as a rough guide, not a precise predictor. For training, combine it with heart rate or perceived effort for a fuller picture.

Frequently Asked Questions

What if I run a half marathon (21.1 km) in 2 hours?

Convert 2 hours to 120 minutes. Enter 120 for time and 21.1 for distance. The pace will be 120 ÷ 21.1 = 5.69 min/km, and speed is 21.1 ÷ (120 ÷ 60) = 10.55 km/h.

Can I use this for walking or cycling?

Yes, the formula works for any activity where you cover a distance in a known time. Just enter the distance and total time for that activity.

How do I convert my pace from min/km to min/mile?

Multiply the pace in min/km by 1.609. For example, 5.00 min/km × 1.609 = 8.05 min/mile. To convert speed from km/h to mph, divide by 1.609 (12.00 km/h ÷ 1.609 = 7.46 mph).

Why does the calculator show “Cannot compute” sometimes?

That happens when the finish time is 0 or the distance is 0, which would mean division by zero. Enter a positive time and a positive distance to get a result.

Is this the same as a treadmill pace?

Yes, if you set the treadmill to a constant speed, your pace is simply the inverse of that speed. For example, 12 km/h on a treadmill equals 5.00 min/km. However, treadmill runs often feel easier than outdoor runs due to lack of wind resistance and terrain.

Should I use this for race prediction?

It gives your current average pace, but race prediction depends on training, fatigue, and course conditions. Use it to see what pace you held in a past race, not to predict a future one. For prediction, consider using a dedicated race predictor that factors in distance and recent performance.
